Platinum nanomaterial catalyst

Release date: 2008- 1 1-25 Source: Petrochemical Science and Technology Network Browse: 79

With the birth of electrochemical preparation method of catalyst, Chinese scientists synthesized a new type of platinum nano-material catalyst, which improved the catalytic activity, stability and efficiency, and was a major breakthrough in the preparation method of platinum nano-material catalyst in China.

Platinum nano-material is a kind of catalyst which can improve the efficiency of important chemical reactions and has good performance. However, due to the backward preparation process, the platinum nanomaterials synthesized by traditional methods have low catalytic efficiency and short service life, which increases the cost in the use process, and platinum is a precious metal with scarce resources and expensive price. Therefore, it is difficult for platinum nano-material catalysts to be widely used at present. Improving the catalytic efficiency is the key factor to reduce and increase the cost of catalyst. After more than one year of experimental research, the School of Chemistry and Chemical Engineering of Xiamen University developed a new electrochemical method to control the surface structure and growth of nanocrystals, and synthesized twenty kinds of tetrahedral platinum nanocrystals.

Tetrahedron is a rare crystallization mode of platinum nanocrystals, and its surface has a high exponential crystal structure. This crystal structure can improve the activity and stability of the catalyst, and its catalytic activity is 2 to 4 times that of commercial platinum nanocrystals, which can improve the catalytic efficiency and prolong the service life.

The new preparation method provides a new idea for the research of platinum nano-material catalyst, and also shows its great application value in fuel cells, petrochemical industry, automobile exhaust purification and other fields.

"For many chemical manufacturers in the United States, a hurricane swept away some of their profits in the third quarter of this year. However, the more serious situation may be the imminent economic recession and the significant impact this crisis may have on their business performance in the fourth quarter of this year and next year. "

It is difficult to keep the high-cost "mountain" by raising prices.

In September, Hurricane Ike landed in the Gulf of Mexico, and many chemical companies suffered heavy losses. When dealing with the impact of this natural disaster on their quarterly business performance, the evaluation criteria of each chemical company are different, which makes the uneven profit more complicated.

Dupont deducted $6543.8+$46 million from the profit; Dow Chemical Company deducted 8 1 10,000 USD; Celanese Company included150,000 USD related to "Ike" in the adjusted profit.

However, even though it was not hit by the hurricane, the profit reported by Dow Chemical Company in the third quarter was still 365,438+0.65,438+0% lower than that of the same period last year. Although the company's net sales increased by 13.4% year-on-year, its raw material and energy costs soared by 48% to $2.6 billion, the largest quarterly increase in the history of Dow Chemical Company. Although the company implemented a 22% price increase, higher product prices and weak market demand still reduced the sales of Dow Chemical Company by 5%.

Last quarter, with a strong sales front, Dow Chemical Company was able to offset the negative impact of sluggish domestic market demand in the United States-70% of its sales revenue came from outside the United States. However, Andrew Liveris, CEO of the company, warned in a report to investors that weak market demand is spreading to other parts of the world. "In our view, the global economic recession will gradually emerge in most of 2009."

Professional chemical producers such as Yabao Company and Rohm & Haas Company are also facing unexpected impacts of high cost. Dmitry Silversteyn, a senior research analyst in charge of tracking professional chemicals in Longbow Research, an investment company, said that product pricing is a good way to save these chemical enterprises from the fatigue of sales growth, but obviously, it is the worst way for enterprises to develop, and it is still necessary to predict the future of the chemical market in the last quarter of this year.

The fundamentals of agricultural chemicals have risen against the trend.

Despite all kinds of pressures, the chemical industry still has some good news. Due to the high commodity prices, chemical enterprises oriented to agricultural applications continue to benefit from strong pricing power. In the third quarter of this year, the profit margins of fertilizer producers Mosaic and Terra Industries both exceeded 20%.

The profit margins of professional chemical manufacturers FMC and Nalco are in sharp contrast with the downward trend of the industry. William Walter, CEO of FMC, attributed the company's profit growth rate of 62.3% to Brazil's strong demand for agricultural products and its sales growth of biopolymers and lithium professional products.

Narko's product sales have increased all over the world, among which Latin America has the highest growth rate, reaching 28.2%. The company's CEO, J.ErikFyrwald, attributed this growth momentum to "high demand in many fields".

Praxair and Air Chemical Products Company, industrial gas suppliers, continued to make steady progress in sales revenue and profit growth, but their profit margins declined. Stephen Angel, CEO of Praxair, predicted in a report to investors that the next few years will be even more difficult. He said, "We expect that in the next few quarters, the output of the United States and Europe will shrink, and the growth rate of Asia and South America will slow down."

I pioneered the clean process of electrochemical synthesis of succinic acid.

Yesterday, I learned from Zhejiang University of Technology that the 3000t/a green electrochemical clean production process research and industrialization project of succinic acid, which was completed by Professor An's research group and Anhui Anqing Hexing Chemical Co., Ltd., attracted the keen attention of many investors. This achievement has passed the appraisal organized by China Petroleum and Chemical Industry Association. Experts in the industry believe that with the maturity and popularization of biodegradable plastic polybutylene succinate (PBS) technology, the succinic acid market as an important raw material will usher in a new round of construction climax.

Succinic acid is widely used, among which biodegradable plastic PBS is the most promising and important application field. The production of 1 ton PBS requires 0.62 tons of succinic acid. Compared with other biodegradable plastics, PBS not only has excellent mechanical properties, but also has reasonable price and huge market demand. At present, the technology of synthesizing PBS biodegradable plastics from succinic acid has been successfully developed at home and abroad. Experts believe that the annual demand for PBS in China will reach more than 3 million tons in the future, and it will consume 6.5438+0.8 million tons of succinic acid. At present, the annual production capacity of succinic acid in China is less than 50 thousand tons, and there is huge room for growth of succinic acid market.

Zhejiang University of Technology is the earliest research unit in China to develop the diaphragm-free electrolytic synthesis technology of succinic acid. Since 1994, Ma Chun 'an's research group has successfully developed pilot-scale and industrial model test technology for electrolytic synthesis of succinic acid without diaphragm, and built the first set of 100 tons/year and 500 tons/year electrochemical industrialization devices for succinic acid in Anhui Sanyuan Chemical General Factory. In 2000, the research group cooperated with Anqing Hexing Company to successfully develop a new type of quaternary lead alloy electrode, which made the whole production process without waste water and waste gas, and achieved the goal of zero emission of green electrochemical production technology and process. In 2006, 3000 tons/year continuous green electrochemical synthesis production line of succinic acid without diaphragm was built. This technology is the first at home and abroad.

Using this process to produce succinic acid, the energy-saving effect is outstanding, the raw material cost is low, the product quality is excellent, and the content is above 99.5%, which completely reaches the food-grade quality index. Practice has proved that using diaphragm-free electrolysis technology instead of traditional diaphragm electrolysis technology can save more than 600 kWh of DC power per ton of succinic acid produced, and the energy-saving efficiency can reach more than 25%. In addition, compared with the traditional route, the recycling of electrolytic mother liquor and the treatment technology of oxygenated acid mist generated by electrolysis in the new process can reduce at least one ton of dibasic acid 15 tons of wastewater and one ton of acidic waste gas 174 cubic meters.

The total demand of polyacrylamide will reach 400 thousand tons.

It is estimated that the total demand for polyacrylamide in China will reach 400,000 tons in 20 10. Among them, the consumption proportion of oil fields will decrease, and the consumption proportion of water treatment and paper making will increase.

Before 1990s, due to technical and market reasons, the production and consumption of polyacrylamide in China were relatively stable. Later, with the wide application in petroleum industry, the output and output of polyacrylamide increased continuously. In 2002, the production capacity and output of polyacrylamide in China were 200,000 tons/year and 6,543.8+500,000 tons respectively. In 2006, the production capacity and output increased to 500,000 tons/year and 320,000 tons respectively.

Although the output of polyacrylamide in China is very large, the quality of polyacrylamide for papermaking can not meet the requirements of domestic paper mills, so domestic paper mills need to import a large amount of polyacrylamide from Taiwan Province Province, Japan and other countries and regions every year. With the increase of paper and paperboard output, the import of polyacrylamide is also increasing year by year. From 2002 to 2006, the average annual growth rate of polyacrylamide import in China was about 15%, and the import volume reached 26,200 tons in 2006. However, with the Japanese Arakawa Chemical Industry Company, Seiko PMC Company and Bomo Chemical Company increasing their investment in the production of polyacrylamide in China, it is predicted that the import of polyacrylamide for papermaking will decrease in the future, and the import of polyacrylamide in China will be about 20,000 tons in 20 10. China's polyacrylamide is exported to more than 70 countries and regions such as South Africa, the United States and Australia. With the rapid growth of polyacrylamide output, the export volume is also increasing year by year. From 2002 to 2006, the average annual growth rate of polyacrylamide export in China was about 13%, and the export volume reached 27,500 tons in 2006. It is predicted that the export volume of polyacrylamide in China will continue to increase in the future, and it will be about 38,000 tons in 20 10.

Polyacrylamide in China is mainly used in the fields of oil exploitation, water treatment and paper making, as well as in the fields of textile, metallurgical sugar making and medicine. In 2006, the apparent consumption of polyacrylamide was about 3 1.87 million tons. Among them, the amount of polyacrylamide in oil exploitation accounts for about 78.5% of the total amount, water treatment accounts for about 1 1%, papermaking accounts for about 7.8%, and textile and other fields account for about 2.7%.

In petroleum exploitation, polyacrylamide can be used as thickener, stabilizer and settling flocculant for drilling mud. Adding polyacrylamide to tertiary oil recovery can increase oil displacement capacity and improve oil recovery; In addition, it can also be used as fracturing fluid additive, retarder, water-oil ratio control agent, temporary plugging agent and so on. At present, polyacrylamide has been widely used in Daqing Oilfield and Shengli Oilfield because of the aging of the early developed oilfields in China. In 2006, the consumption of polyacrylamide in oil exploitation in China was about 250,000 tons. It is predicted that more oil fields will start to use polyacrylamide in large quantities in the future. From 2006 to 20 10, the demand for polyacrylamide in this field will increase at a rate of about 5%, and the demand will reach about 307,000 tons by 20 10. Polyacrylamide is used as flocculant in water treatment, which mainly includes coagulation and clarification of suspended particles in domestic water with activated carbon in raw water treatment; Used for sludge dewatering in sewage treatment; It is an important formula medicament in industrial water treatment. At present, many large and medium-sized cities use polyacrylamide flocculant as a supplement when water supply is tight or water quality is poor. Polyacrylamide has become the main flocculant in sewage treatment. In 2006, the consumption of polyacrylamide in the field of water treatment in China was about 35,000 tons. With the acceleration of the construction of water pollution control projects in China, the consumption of polyacrylamide will continue to increase in the future. It is estimated that by 20 10, the demand for polyacrylamide in this field will reach about 48,000 tons. Polyacrylamide is mainly used as retention aid in paper industry, and cationic polyacrylamide has the best retention aid effect. China is a big country in paper production and consumption. In 2006, the output of paper and paperboard reached 65 million tons, and the consumption of polyacrylamide was about 25 thousand tons. It is estimated that by 20 10, China's paper production capacity will reach 94 million tons/year, and the demand for polyacrylamide in this field will reach about 40 thousand tons.

In other fields, polyacrylamide can be used in textile, mining and construction. In 2006, the consumption of polyacrylamide in these fields was about 8700 tons, and it is predicted that the demand of polyacrylamide will reach 10 tons by 20 10. To sum up, the total demand of polyacrylamide in China will reach about 400,000 tons in 20 10.

The EU will introduce the Chemical Classification and Labelling Act.

Release time: 2008-11-21Source: China Quality News Network, visit: 70.

As the EU is about to implement the Regulation on Registration, Evaluation and Licensing of Chemicals (REACH Regulation for short) for traders of chemical substances and preparations in the EU, it will promulgate regulations on classification and labeling methods of chemicals. The new regulations will be consistent with the United Nations Globally Harmonized System of Classification and Labelling of Chemicals. The European Commission adopted a bill on the classification, labeling and packaging of chemical substances and mixtures, which has been incorporated into the classification standards and labeling rules recognized by the United Nations.

At present, all suppliers of chemical substances must classify and label the substances according to the Dangerous Substances Guide (67/548/EEC) before they can be sold in the market. The original "new substances" notification system has been replaced by REACH regulations. The REACH regulation is based on the existing regulations, but it does not stipulate the standards or responsibilities of classification and labeling, and only refers to the relevant provisions of the Guide to Dangerous Substances and the Guide to Dangerous Preparations (1999/45/EC).

For labels, traders must provide the name, address and telephone number of suppliers, information that can identify substances or mixtures, danger signs, danger descriptions, precautions and supplementary information about dangers.

The scope of application of the bill is as close as possible to the current EU system, and it is complementary to the new REACH regulation, which will replace the "classification and labeling catalogue" of the regulation, but some technical amendments will be made. Compared with the current system, the quantity of classified substances under the new system will be similar to that at present.

Laws and regulations have a transitional period, during which all laws and regulations are applicable. According to the regulations, after the bill comes into effect, the time limit for substance reclassification is 2065438+65438 10+065438+30, and the time limit for mixture reclassification is 2065438+365438+May 0, 2005. The current directive on classification, labeling and packaging will be abolished on June 1 2065. During the transition period, enterprises can adopt the classification and labeling system described in existing laws or regulations.

According to the requirements of the Classification and Labelling of Chemicals Act of the European Union, the inspection and quarantine department reminds relevant enterprises to keep abreast of the latest developments in the European Union and actively take effective measures to deal with the Act.

China still needs to import a lot of ethylene glycol due to global overcapacity.

Release date: 2008- 10-24 Source: Medical Economic News Browse: 62

The global ethylene glycol market is setting off a climax of capacity expansion. It is estimated that the total consumption of ethylene glycol in 20 10 will reach 210.88 million tons/year, and the total production capacity will reach 27.093 million tons/year. Overcapacity in the next few years is a foregone conclusion. At the same time, the new production capacity in the Middle East and the rise of China's Asian consumption places will greatly impact the world ethylene glycol market structure and make the supply and demand structure undergo major changes.

Capacity expansion projects gather in the Middle East.

Dow Chemical is currently the largest ethylene glycol producer in the world, with a production capacity of 3.2 million tons/year, accounting for 18.8% of the global total production capacity. Production plants are mainly distributed in the United States, Canada, the Netherlands and the United Kingdom. The second largest producer is Saudi Oriental Petrochemical Company, with a production capacity of 654.38+0.565 million tons/year, accounting for 9.2% of the world. The third place is Shell Chemical Company, with a production capacity of 995,000 tons/year, accounting for about 5.9% of the global total production capacity. Production plants are mainly distributed in Canada, the United States and the Netherlands. By 20 10, the ethylene glycol production capacity of Saudi Oriental Petrochemical Company will exceed 3.3 million tons/year, thus replacing Dow Chemical as the largest ethylene glycol producer in the world.

In recent years, the world ethylene glycol production base is accelerating to concentrate in the Middle East. From 2006 to 20 10, the global ethylene glycol production capacity exceeded 8 million tons/year, of which more than 5 million tons/year were concentrated in Saudi Arabia, Iran, Kuwait and other Middle Eastern countries. For example, the 600,000-ton/year project of Kuwait Aquatech II, the 700,000-ton/year project of Saudi Oriental Petrochemical IV and the 600,000-ton/year project of Saudi Yanbu III are all planned to be put into production this year. Hager) The 500,000-ton/year project of 50 Island and the 400,000-ton/year project of Iran National Petrochemical Company are planned to be put into production in the second half of this year and the fourth quarter of 2009 respectively; Saudi Aramco 800,000 tons/year project and Saudi Jubail No.3 675,000 tons/year project are planned to be put into production in the second quarter of 2009 and the fourth quarter of 20 10 respectively. In addition, Venezuela's ExxonMobil 400,000 tons/year project will be put into production in the second quarter of next year; Singapore Shell's 500,000-ton/year project will be put into production in the fourth quarter of next year. The newly-increased ethylene glycol production capacity in the Middle East is basically used for export, mainly to China-dominated Asia.

Small producers will be eliminated.

There are many new ethylene glycol projects in the world, which makes this market gradually show a pattern of oversupply. According to industry analysis, in 2007, the global ethylene glycol production capacity reached19.408 million tons/year, and the total consumption was17.6 million tons/year, and the production capacity has exceeded the consumer demand. Due to the increasing demand of downstream polyester for ethylene glycol, it is estimated that the world consumption of ethylene glycol will increase at an average annual rate of 4.8% in the next few years, and by 20 10, the total global consumption of ethylene glycol will reach 218800 tons/year. However, in 20 10, the global ethylene glycol production capacity will reach 27.093 million tons/year, which greatly exceeds the total consumption. Therefore, it is a foregone conclusion that supply exceeds demand in the global ethylene glycol market, and this situation of supply exceeding demand will continue for a long time.

It is predicted that some installations in the United States, Europe and Japan will be forced to close due to weak competitiveness, among which American installations will account for the majority.

The increase of ethylene glycol production mainly depends on the digestion and absorption in the Asian market centered on China. After the situation of oversupply is formed, the contract price and spot price of ethylene glycol in Asia will fall. The pressure of falling prices will make Asian ethylene glycol producers with China as their main export market face enormous survival pressure, and will also affect ethylene glycol producers in China. Despite the freight advantage and tariff protection, it will be difficult for some small ethylene glycol producers to avoid being eliminated.

China still needs a lot of imports.

On the whole, the global ethylene glycol production capacity has been surplus, but the output in Asia can't meet the actual demand, and it needs to be imported in large quantities every year, especially in China. As the largest consumer in the world, China will account for 30% of the world's consumption in 2008, and half of its export market will be concentrated in China. From 2008 to 20 10, China will increase its production capacity by 22 10000 tons/year, of which 16 10000 tons/year has been approved. It is estimated that the total ethylene glycol production capacity in China will be about 2.5 million tons/year in 2008 and will reach about 4 million tons/year in 20 10. In 2008, the total demand of ethylene glycol in China will reach about 6.36 million tons/year, and it will reach about 765,438+10,000 tons/year in 20 10.

In the next few years, China will become the market that ethylene glycol manufacturers compete to seize. With the commissioning of large-scale ethylene glycol projects in Asia, the long-term contradiction between supply and demand of ethylene glycol products in this region will be alleviated to some extent, but the gap between supply and demand is still large. Facing the rapidly expanding markets in Asia and China, major companies in the world are stepping up the construction and expansion of ethylene glycol production capacity. In addition to Canada, the United States, South Korea and Japan, which traditionally export ethylene glycol to China, the share of ethylene glycol produced by Saudi Arabia and other Middle Eastern countries based on their cheap ethane raw materials in China market is increasing rapidly.

The 800,000-ton methanol project of China Shipping Chemical started.

Release date: 2008-1117 Source: China Coal Chemical Network Browse: 46.

165438+1October 12 CNOOC's 800,000-ton/year natural gas methanol project started construction in Hainan Dongfang Chemical City, which is a downstream supporting project for the development of Ledong gas field with a total investment of 10 billion yuan. According to the overall schedule of the project, it will be put into production at the end of 20 10+00.

The main unit of this project adopts British DAVY process technology, and the total energy consumption per ton of methanol is 3 1.4 Ji Jiao, which is far lower than the energy consumption index of 36 Ji Jiao for domestic medium-sized methanol plants and reaches the advanced level of international large-scale methanol plants. The designed capacity of the project is 2500 tons of methanol/day, and the product quality standard can reach the American "AA" standard.

How will the substantial increase in methanol production capacity in China and the Middle East affect the Asian market? What kind of competition pattern will China's coal-to-methanol and Middle East's natural gas methanol face? How can traditional applications such as methanol to acetic acid and formaldehyde and new applications such as methanol to dimethyl ether, olefin and alcohol ether fuel digest such a huge methanol production capacity? The "2008 Asian Methanol and Derivatives Summit" hosted by Shanghai Yahua Business Consulting Co., Ltd. and co-organized by Nanjing Chemical Industry Park will be held in Nanjing on June 27-28, with the focus on Nanjing Chemical Industry Park. Tel: 021-51386466,021-33199670.

Yahua Consulting believes that now is the best time to start the methanol project, the workload of the design and construction unit is not large, and the project quality is guaranteed; Raw materials such as steel, infrastructure and equipment are cheap; The completion of this project will usher in a new round of methanol industry boom cycle.
