Fatty acid methyl esters were prepared by esterification in a fixed bed reactor from methanol and fatty acids in palm oil deodorizer distillate (PODD) using a cation exchange resin as catalyst.
In the reaction process, the free fatty and resin acids react with the alcohol, with the aid of the acid catalyst, to yield the desired ester products.
