摘要： The present invention describes a method of producing fatty acid alkyl esters and glycerin implementing, in a reaction section, a set of transesterification reactions between a vegetable or animal oil and an aliphatic monoalcohol, and using a heterogeneous solid catalyst, comprising: a) a stage of recontacting the effluent coming from the reaction section, and separated from the excess alcohol, with a glycerin phase, b) a stage of mixing said effluent with said glycerin phase, and c) a glycerin phase decantation stage. The supernatent ester phase obtained after decantation is then optionally sent to a coalescer, also allowing separation of the glycerin, then to a purification stage by adsorption on solids.
