<p>Preparation of alkyl esters of fatty acid and glycerol (I) comprises: at least a reactive step (a) comprising contacting a charge having a plant and/or animal oil and an alcohol to obtain an effluent comprising alkyl esters, glycerol and alcohol; and a separation step (b) comprising separating a portion of the effluent, where (b) comprises a membranous separation with the use of at least a membrane (II) permeable to alcohol. Preparation of alkyl esters of fatty acid and glycerol (I) comprises: at least a reactive step (a) comprising contacting a charge having a plant and/or animal oil and an alcohol, in presence of a heterogeneous catalyst, to obtain an effluent comprising alkyl esters, glycerol and alcohol; and a separation step (b) comprising separating a portion of the effluent to separate an effluent rich in alcohol from an effluent rich in alkyl esters, where (b) comprises a membranous separation with the use of at least a membrane (II) permeable to alcohol.</p> |
