Abstract

A process for producing biological diesel oil by fixed enzyme method is carried out by taking sodium alginate, kaoline, glutaraldehyde, gelatin and lactose as co-fixer, fixing the lipase, piling the spherical fixed enzyme in filled bed columnar reactor naturally, alcoholyzing animal and plant oil fatty with biological diesel oil as solvent and producing biological diesel oil. It is cheap, has less consumption and by product and better quality. It can be used for continuous production.

Description

technical field

[0001] The invention relates to a method for producing biodiesel, in particular to a method for catalyzing alcoholysis of animal and vegetable oils into biodiesel by immobilized lipase method in a non-aqueous phase system. Background technique

[0002] Diesel is the main power fuel for many large vehicles such as trucks, diesel locomotives and generators. It has the advantages of high power and low price. The demand for diesel in my country is very large, and the growth rate of diesel demand has reached more than 6%, which is much higher than Gasoline growth rate (3.2%).

[0003] The main problem of diesel application is low combustion efficiency and serious air pollution. In order to solve the problem of fuel oil exhaust pollution and the deteriorating environmental pressure, people began to study the use of other energy sources such as fuel alcohol fuel instead of gasoline. Currently, fuel alcohol has a considerable proportion in North America, such as the ...
