Title (EN) PROCESS FOR THE PREPARATION OF BIODIESEL
(FR) PROCÉDÉ DE PRÉPARATION DE BIODIESEL
Abstract: front page image
(EN)The invention concerns a process for the preparation of biodiesel which comprises esterification and/or trans-esterification of fatty acids and/or glycerides contained in vegetable oils and /or animal fats in the presence of an alkyl alcohol and a catalyst, in order to obtain a mixture of methyl esters and glycerin, subsequently separated. The process of the invention, allows the use of vegetable oils and/or animal fats with whatsoever acidity content and the avoidance of the formation of soaps and liquid effluents.
(FR)La présente invention concerne un procédé de préparation de biodiesel qui comprend l’estérification et/ou la transestérification d’acides gras et/ou de glycérides contenus dans des huiles végétales et/ou des matières grasses animales en présence d’un alcool alkylique et d’un catalyseur, en vue d’obtenir un mélange d’ester méthylique et de glycérine, qui seront ensuite séparés. Le procédé de l'invention permet l’utilisation d’huiles végétales et/ou de matières grasses animales, quelle que soit leur teneur en acidité, et d’éviter la formation de savons et d’effluents liquides.
