METHOD OF CONVERTING GREASE CONTAINING HIGH CONTENT OF FREE FATTY ACIDS TO FATTY ACID ESTERS AND CATALYSTS FOR USE IN SAID METHOD

摘要

A method of producing fatty acid esters from a composition comprising glycerides and at least 10% by weight of free fatty acids (FFA), the method comprising incubating a plurality of micro- or nano-sized catalysing particles with the composition, to catalyse the conversion of FFA to fatty acid esters, such that at least 80% of the FFA are converted to fatty acid esters.
