Producing fatty acid methyl- or ethyl-ester, useful as biodiesel, comprises esterification of free fatty acids, which are derived from natural fats or oils, with methanol or ethanol

摘要

Producing fatty acid methyl ester or fatty acid ethyl ester, comprises esterification of free fatty acids (which are derived from natural fats or oils) with methanol or ethanol, where the reaction water is separated from the reaction equilibrium using an adsorbent, which directly absorbs the reaction water from the reaction mixture.
