Title:
METHOD FOR PRODUCING BIO-DIESEL USING ANIMAL LIPIDS AND REMOVING SULFUR
Document Type and Number:
WIPO Patent Application WO/2023/120912
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a method for producing bio-diesel, the method comprising the steps of: mixing animal lipids, a solvent, and a catalyst in a reactor to cause an esterification reaction, and producing a crude bio-diesel; removing the solvent from the crude bio-diesel through first vacuum distillation; removing glycerol from the crude bio-diesel through layer separation; removing the catalyst from the crude bio-diesel by washing with water; and removing a sulfur component from the crude bio-diesel from which the solvent, the glycerol, and the catalyst have been removed, through second vacuum distillation, and producing a high-purity bio-diesel.
