Abstract
(EN)
Disclosed is a process for preparing biodiesel by online dehydrated lipase catalyzing renewable grease. In this method, a short chain alcohol ROH is used as a reaction acyl acceptor; a lipase is used as a catalyst to catalyze a transesterification reaction of an oil and grease stock with the above mentioned short chain alcohol to synthesize biodiesel; online dehydration is carried out with a membrane or molecular sieve during the whole process or part of the reaction process; this online dehydration greatly simplifies the operation, and provides good economic and environmental benefits.

La présente invention concerne un procédé d'élaboration de biodiesel par catalyse par lipase déshydratée en ligne de matières grasses renouvelables. Dans ce procédé, un alcool ROH à chaîne courte joue le rôle d'accepteur de réaction d'acylation ; une lipase est utilisée en tant que catalyseur pour catalyser une réaction de transestérification de matières grasses et d'huiles de départ par l'alcool à chaîne courte susmentionné dans le but de synthétiser du biodiesel ; la déshydratation en ligne est mise en œuvre à l'aide d'une membrane ou d'un tamis moléculaire pendant la totalité du processus ou une partie du processus réactionnel ; cette déshydratation en ligne simplifie considérablement l'opération et présente des avantages économiques et environnementaux satisfaisants.
