Abstract
The present invention describes a method of producing fatty acid alkyl esters and glycerin implementing a set of transesterification reactions between a vegetable or animal oil and an aliphatic monoalcohol in the presence of a heterogeneous solid catalyst so as to obtain an effluent comprising at least alkyl esters, free glycerol, bonded glycerol and alcohol, wherein at least one stage of separation of at least a portion of the effluent is carried out in order to separate the ester produced and the bonded glycerol, said separation occurring through a membrane.
