Inform the hotel to recycle the waste oil in the trash can to produce biodiesel. How is biodiesel made?

Biodiesel is made from animal oil and vegetable oil through a special process. It mainly uses animal and vegetable oils as raw materials to prepare long-chain fatty acid lipid chemicals according to transesterification reaction. It has the characteristics of degradable, non-toxic and clean energy. It is a green gasoline substitute and has broad application prospects.

Can waste oil be used to make biodiesel?

Because Japan cut off the source of saliva oil according to the recovery of waste oil, the recovered waste engine oil is either refined into biodiesel and turned into green energy, or turned into production materials for the production and manufacturing of industrial products, in either case, the waste utilization is guaranteed. Waste edible oil can be converted into microbial diesel by esterification and transesterification. In order to improve the production efficiency of diesel oil, it is more conducive to improve the production efficiency of diesel oil by choosing enzyme immobilization technology and adding industrial methanol in the chemical reaction process.

Is the cost of refining biodiesel high?

Biodiesel raw material is an important part of biodiesel production. In the process of biodiesel production, the cost of raw materials accounts for more than 70% of the cost. Therefore, in the process of biodiesel production, finding large-scale, low-cost, pollution-free and improved utilization rate of raw oil is the core content and key issue of biodiesel industry development. At present, all countries in the world have chosen suitable raw materials to produce biodiesel according to the basic national conditions of China. Due to the increase of transgenic soybean production, soybean oil is widely planted in the United States.

Therefore, soybean oil is used as raw material to produce biodiesel, and oil palm is planted in Southeast Asia according to the local soil climate. Therefore, cottonseed oil is used to develop biodiesel industrial chain: Europe and other countries in the world use edible oil in vegetable oil to produce biodiesel. Especially in Germany, the total area of rape cultivation is wide: the key in Japan is to choose cheaper waste edible oil to produce biodiesel. China has a vast territory and rich products. There are plenty of raw materials to produce biodiesel. It is of great practical significance to scientifically study the advantages and disadvantages of preparing biodiesel from different raw materials for discovering the advantages of biodiesel. There are four kinds of raw materials to produce biodiesel.
