The refining of biodiesel is made from animal oil and vegetable oil by a special process. It mainly uses animal and vegetable oil as raw materials to prepare long-chain fatty acid lipids by transesterification. It has the characteristics of being degradable, non-toxic and clean energy, and is a green and environmentally-friendly gasoline substitute with broad application prospects.

can waste oil be used to make biodiesel?

because Japan cut off the root of saliva oil according to the recycling of waste oil, the recycled waste engine oil is either refined into biodiesel, turned into green energy, or incarnated as means of production for the production and manufacturing of industrial products, in either case, the waste utilization is guaranteed. Waste cooking oil can be converted into microbial diesel oil according to esterification and transesterification. In order to improve the production efficiency of diesel oil, it is more beneficial to choose enzyme immobilization technology and add industrial methanol in the chemical reaction process to improve the production efficiency of diesel oil.

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 71% of the cost. Therefore, in the process of biodiesel production, it is the core content and key problem for the development of biodiesel industry to find raw oil with large scale, low price, zero pollution and improved utilization rate. At present, according to the basic national conditions of China, all over the world have chosen suitable raw materials to produce biodiesel. Soybean oil is widely planted in the United States due to the increase in production of genetically modified soybeans.

Therefore, soybean oil is used as raw material for biodiesel production, and oil palm is planted in Southeast Asia according to the local soil climate. Therefore, cottonseed oil is used to develop biodiesel industry chain: countries in Europe and the world use edible oil in vegetable oil to produce biodiesel. Especially in Germany, the total area of rapeseed cultivation is wide: the key in Japan is to choose cheaper waste cooking oil to produce biodiesel. China has a vast territory and rich products. Raw materials for biodiesel production are sufficient. Scientific research on the advantages and disadvantages of biodiesel from different raw materials is of key and practical significance for finding the advantages of biodiesel. There are four kinds of raw materials for biodiesel production.
