Abstract[English]
The present invention relates to a process for enzymatic (trans)esterification/esterification of free fatty acids and glycerides. In particular, the invention relates to this process using a drying operation for water removal from enzyme reaction mixture continuously or by separating the glycerol phase from the reaction mixture, then drying the glycerol phase and recirculating to reform the reaction mixture, especially in biodiesel applications, which facilitates reduction of FFA in the biodiesel.[French]
La présente invention concerne un procédé de (trans)estérification/estérification enzymatique d'acides gras libres et de glycérides. En particulier, l'invention concerne la mise en oeuvre de ce procédé à l'aide d'une opération de séchage pour l'élimination d'eau d'un mélange réactionnel enzymatique en continu ou par séparation de la phase glycérol du mélange réactionnel, puis séchage de la phase glycérol et recirculation pour reformer le mélange réactionnel, en particulier dans des applications biodiesel, ce qui permet la réduction de FFA dans le biodiesel.
