Title:
METHOD FOR PREPARING FATTY ACID ALKYL ESTER USING FAT
Document Type and Number:
WIPO Patent Application WO/2015/012538
Kind Code:
A1
Abstract:
Disclosed is a method for preparing fatty acid alkyl ester for a biodiesel fuel by reacting alcohol with fatty acid, which is prepared by reacting a raw material containing fat with water. The method for preparing fatty acid alkyl ester for a biodiesel fuel, comprises the steps of: subjecting water and a raw material containing fat to a hydrolysis reaction at a temperature of 200 to 280℃ and a pressure of 30 to 80 bars, thereby preparing fatty acid and glycerin; layer-separating the glycerin and the fatty acid; and subjecting the separated fatty acid and alcohol to an esterification reaction at a temperature of 200 to 350℃ and normal pressure to a pressure of 35 bars.
