Abstract
(EN)
The document relates to a process for producing fatty acid alkyl esters, the process comprising reacting a feedstock that includes one or more fatty acid glycerol esters or one or more fatty acids or a mixture thereof with a C5 to C10 alcohol in the presence of a catalyst at a substantially higher temperatures of 100° C or more, the catalyst including a catalyst composition comprising oxides, mixed oxides, silicates or sulphates of two or more of silica, aluminum, iron, calcium, magnesium, sodium and potassium.
(FR)
L'invention concerne un procédé de production d'esters alkyliques d'acide gras consistant à : faire réagir une charge comprenant un ou plusieurs esters de glycérol d'acide gras ou un ou plusieurs acides gras ou un mélange de ceux-ci avec un alcool C5-C10 en présence d'un catalyseur à des températures sensiblement supérieures à 100° C ou plus, le catalyseur comprenant une composition catalytique constituée d'oxydes, d'oxydes mélangés, de silicates ou de sulfates d'au moins deux éléments de silice, d'aluminium, de fer, de calcium, du magnésium, de sodium et de potassium.
