Abstract
A method for producing fatty acid alkyl esters from a feedstock, involving:(a) saponifying the feedstock with an alkali to form a saponified feedstock,(b) removing the water from the saponified feedstock to form a dried saponified feedstock containing no more than about 10% water,(c) esterifying the dried saponified feedstock with an alcohol in the presence of an inorganic acid catalyst to form fatty acid alkyl esters even with water present at levels up to about 3 wt %, and(d) recovering the fatty acid alkyl esters.
