Title (EN) A PROCESS FOR PRODUCTION OF BIODIESEL
(FR) PROCÉDÉ DE PRODUCTION DE BIODIESEL
Abstract:
(EN) A process for producing alkyl esters is disclosed. The process includes reacting a feedstock that includes one or more fatty acid glycerol esters or one or more fatty acids or mixture thereof with a C1 to C4 alcohol in the presence of fly ash as a catalyst. A catalyst for the production of alkyl esters is also disclosed.
(FR) L'invention concerne un procédé de production d'esters alkyliques. Le procédé consiste à mettre à réagir une charge, qui comprend un ou plusieurs esters d'acides gras du glycérol ou un ou plusieurs acides gras ou un mélange de ceux-ci avec un alcool C1 à C4, en présence d'une cendre volante utilisée comme catalyseur. L'invention concerne également la production d'esters alkyliques.
