METHOD FOR PRODUCING FATTY ACID ALKYL ESTER AND/OR GLYCERINE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a fatty acid alkyl ester and/or glycerine suppressing reduction of activity of a solid catalyst used in an ester-exchange reaction of fats and oils with alcohols.

SOLUTION: The method for producing the fatty acid alkyl ester and/or glycerine includes the dissolved oxygen concentration reduction step for reducing the dissolved oxygen concentration of the fats and oils and/or the alcohols before the reaction step for reacting the fats and oils with the alcohols in the presence of the solid catalyst.
