Document Type and Number:
Japanese Patent JP2009535442
Kind Code:
A
Abstract:
A method and an apparatus for preparing fatty acid alkyl ester for bio-diesels are disclosed, wherein fatty acid, specifically fatty acid distillate reacts with alcohol, without a catalyst. The method does not require the purification process of the catalyst and glycerin, and has the superior conversion ratio of fatty acid. The method for preparing fatty acid alkyl ester for bio-diesel fuels comprises the step of esterifying fatty acid raw material with alcohol, under a temperature of 200 to 350° C. and a pressure of atmospheric pressure to 10 bar. The apparatus for preparing fatty acid alkyl ester for bio-diesel fuels, comprises: the first reactor for esterifying fatty acid raw material with alcohol under a temperature of 200° C. to 350° C. and a pressure of atmospheric pressure to 10 bar and for converting 80 to 90% of total fatty acid into fatty acid alkyl ester; and the second reactor for converting remaining fatty acid unconverted at the first reactor into fatty acid alkyl ester.
