Title
(EN) CHROME-FREE COPPER CATALYSTS FOR FATTY ESTER HYDROGENOLYSIS/HYDROGENATION
(FR) CATALYSEURS DE CUIVRE EXEMPTS DE CHROME POUR HYDROGÉNOLYSE/HYDROGÉNATION D'ESTERS GRAS
Abstract
(EN) A method of preparing a calcined hydrogenolysis/hydrogenation catalyst includes mixing a copper-containing material, manganese-containing material, sodium aluminate, and water to obtain an aqueous slurry; contacting the aqueous slurry with a caustic material to form a precipitate in a caustic aqueous slurry; removing the precipitate from the caustic aqueous slurry; and removing residual water from the precipitate to form a dried precipitate; calcining the dried precipitate to form the calcined hydrogenolysis/hydrogenation catalyst exhibiting a Brunauer-Emmett-Teller ("BET") surface area of about 5 m2/g to about 75 m2/g. The calcined hydrogenolysis/hydrogenation catalyst may include a spinel structure crystallite size of about 15 nm or less. The calcined hydrogenolysis/hydrogenation catalyst may include a tenorite crystallite size of about 20 nm to 30 nm.
(FR) L'invention concerne un procédé de préparation d'un catalyseur d'hydrogénolyse/hydrogénation calciné, le procédé consistant à mélanger une substance contenant du cuivre, une substance contenant du manganèse, de l'aluminate de sodium et de l'eau afin d'obtenir une suspension aqueuse ; à mettre en contact la suspension aqueuse avec une substance caustique afin de former un précipité dans une suspension aqueuse caustique ; à retirer le précipité de la suspension aqueuse caustique ; et à retirer l'eau résiduelle du précipité afin de former un précipité séché ; à calciner le précipité séché afin de former le catalyseur d'hydrogénolyse/hydrogénation calciné présentant une surface Brunauer-Emmett-Teller (« BET ») comprise entre environ 5 m2/g et environ 75 m2/g. Le catalyseur d'hydrogénolyse/hydrogénation calciné peut présenter une taille de cristallite à structure en spinelle égale ou inférieure à environ 15 nm. Le catalyseur d'hydrogénolyse/hydrogénation calciné peut présenter une taille de cristallite de ténorite comprise entre environ 20 nm et 30 nm.
