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 glycerin phase introduction stage, b) an excess alcohol evaporation stage, and c) a glycerin phase decantation stage. The supernatant 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. This improved method prevents microemulsion formation.
