Method for metathesis of a fatty acid ester or fatty acid esters
The present invention concerns a method for the metathesis of an olefin or olefins and, more specifically, of one or more fatty acid esters comprising at least one unsaturation.The method according to the invention comprises bringing at least one fatty acid ester into contact with a metathesis catalyst, in which the fatty acid ester is treated by a sorbent before being brought into contact with the metathesis catalyst, the sorbent having a pH lower than 6.0 and comprising at least 65% by weight of SiO2, the weight percentage being given relative to the total weight of sorbent.
