Title (EN) IMPROVED PROCESS FOR PREPARING FATTY ACID ALKYLESTERS USING AS BIODIESEL
(FR) PROCEDE AMELIORE PERMETTANT DE PREPARER DES ALKYLESTERS D'ACIDES GRAS UTILISABLES EN TANT QUE BIODIESEL
Abstract: front page image
(EN)Fatty acid alkyl esters suitable for use as biodiesel are produced by a single step esterification of free fatty acids and transesterification of triglycerides from vegetable oils or animal fats or combinations thereof with a lower alcohol (e.g. methanol) in presence of alkyl Tin oxide as catalyst. The ester thus produced is purified by distillation, treatment with an adsorbent, washing with water or combination thereof to give esters suitable for use as biodiesel.
(FR)La présente invention concerne des alkylesters d'acides gras pouvant être utilisés en tant que biodiesel, lesquels sont produits en une seule étape d'estérification des acides gras et de transestérification des triglycérides à partir d'huiles végétales ou de graisses animales ou de combinaisons de celles-ci avec un alcool inférieur (par exemple, du méthanol) en présence d'oxyde d'étain alkylé en tant que catalyseur. L'ester ainsi produit est purifié par distillation, traité au moyen d'un adsorbant, laver avec de l'eau, afin d'obtenir des esters pouvant être utilisés en tant que biodiesel.
