Title (EN) IMPROVED PROCESS FOR THE PREPARATION OF FATTY ACID ALKYL ESTERS (BIODIESEL) FROM TRIGLYCERIDE OILS USING ECO-FRIENDLY SOLID BASE CATALYSTS
(FR) PROCÉDÉ AMÉLIORÉ POUR LA PRODUCTION D'ESTERS ALKYLIQUES D'ACIDE GRAS (BIOGAZOLE) À PARTIR D'HUILES TRIGLYCÉRIDIQUES AU MOYEN DE CATALYSEURS BASIQUES SOLIDES RESPECTUEUX DE L'ENVIRONNEMENT
Abstract: front page image
(EN)This invention relates to an improved process for the preparation of green fatty acid methyl esters (FAME; commonly called as biodiesel) from different triglyceride oils using mixed metal oxides derived from layered double hydroxides (referred here as LDHs) as reusable solid heterogeneous base catalysts. This process uses very low alcohohoil molar ratio and catalyst and/or products are easily separable after the reaction through simple physical processes. The properties of thus obtained biodiesel meet the standard biodiesel values and can directly be used as transport fuel.
(FR)Cette invention concerne un procédé amélioré pour la préparation d'esters méthyliques d'acide gras (EMAG, couramment désignés par biogazole) verts à partir de différentes huiles triglycéridiques au moyen d'oxydes de métaux mixtes dérivés d'hydroxydes doubles lamellaires (désignés ici par HDL) sous forme de catalyseurs basiques hétérogènes solides réutilisables. Ce procédé emploie un très faible rapport molaire alcool-huile et le catalyseur et/ou les produits sont facilement séparables après la réaction par des procédés physiques simples. Les propriétés du biogazole ainsi obtenu respectent les valeurs de biogazole standard et il peut être directement utilisé comme carburant de transport.
