Title (EN) HETEROGENEOUS CATALYSTS FOR MONO-ALKYL ESTER PRODUCTION, METHOD OF MAKING, AND METHOD OF USING SAME
(FR) CATALYSEURS HÉTÉROGÈNES POUR LA PRODUCTION D'ESTERS MONOALKYLIQUES, LEUR PROCÉDÉ DE FABRICATION ET LEUR PROCÉDÉ D'UTILISATION
Abstract:
(EN) A heterogeneous catalyst for use in esterification and/or transesterification reactions is provided having the formula AxB2-χO4-χ, where x is between 0.25 and 1.2, A is selected from calcium, magnesium, strontium, or barium, and B is selected from manganese, cerium, titanium, zirconium, silicon, tin or germanium. The heterogeneous catalyst is formed by co-precipitating the corresponding nitrates of the catalyst materials with ammonium carbonate to form a precipitated product which is then calcined. The heterogeneous catalysts can be used to make mono-alkyl ester fuel from feedstocks containing waste oils, fats and grease in the presence of water and/or free fatty acids.
(FR) L'invention porte sur un catalyseur hétérogène destiné à être utilisé dans des réactions d'estérification et/ou de transestérification, représenté par la formule AxB2-xO4-x, où x est compris entre 0,25 et 1,2, A est choisi parmi le calcium, le magnésium, le strontium ou le baryum et B est choisi parmi le manganèse, le cérium, le titane, le zirconium, le silicium, l'étain ou le germanium. Le catalyseur hétérogène est formé par coprécipitation des nitrates correspondants des matières du catalyseur avec du carbonate d'ammonium, pour former un produit précipité qui est ensuite calciné. Les catalyseurs hétérogènes peuvent être utilisés pour fabriquer un carburant ester mono-alkylique à partir de charges contenant des huiles, matières grasses et graisses usées en présence d'eau et/ou d'acides gras libres.
