Title:
METHOD FOR PRODUCING BIOFUEL
Document Type and Number:
WIPO Patent Application WO/2020/022143
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a biofuel that involves reacting a lower alcohol and an animal/vegetable fat/oil raw material that includes free fatty acid in the presence of a solid acid catalyst, wherein the amount of lower alcohol used is kept low and an esterification reaction of the free fatty acid and the lower alcohol is conducted selectively to reform the animal/vegetable fat/oil. [Solution] A method for producing a biofuel that involves using, as a solid acid catalyst, a catalyst selected from SiO2/Al2O3 solid acid catalysts, SiO2/Al2O3 solid acid catalysts in which some of the aluminum has been introduced into mesoporous silica, Al2O3/B2O3 solid acid catalysts, and sulfated zirconia solid acid catalysts, the method being conducted at a molar ratio of free fatty acid and lower alcohol of 1-6.
