Title:
METHOD FOR PREPARING BIODIESEL
Document Type and Number:
WIPO Patent Application WO/2017/012445
Kind Code:
A1
Abstract:
A method for preparing biodiesel takes the form of a preceding enzyme reaction and a subsequent alkaline reaction. The enzyme reaction is mainly an esterification reaction, and the alkaline reaction is mainly a transesterification reaction. A crude ester product with an acid value of 0.5-2.5 mg KOH/g obtained from the step of the enzyme reaction is supplied to the step of the alkaline reaction. The product obtained from the alkaline reaction is separated and purified to obtain the biodiesel. This method is capable of producing high quality biodiesel with a lower production cost and a shorter production period and is suitable for large scale production applications.
