Patent

CA 2316844

A process for the preparation of a cobalt-containing catalyst or catalyst precursor, comprising (a) mixing (1) titania or a titania precursor, (2) a liquid, and (3) a cobalt compound, which is at least partially insoluble in the amount of liquid used, to form a mixture, (b) shaping and drying of the mixture thus-obtained, and (c) calcination of the composition thus-obtained. A catalyst or catalyst precursor obtainable by the process as defined, and a process for the preparation of hydrocarbons comprising contacting a mixture of carbon monoxide and hydrogen with the catalyst as defined.

L'invention concerne un procédé pour la préparation d'un catalyseur renfermant du cobalt ou un précurseur de catalyseur qui consiste a) à mélanger 1) de l'oxyde de titane ou un précurseur de l'oxyde de titane, 2) un liquide et 3) un composé de cobalt qui est au moins partiellement insoluble dans la quantité de liquide utilisée pour former un mélange, b) à former et sécher le mélange obtenu et c) à calciner la composition obtenue. Font aussi l'objet de cette invention un catalyseur ou un précurseur de catalyseur pouvant être obtenu par ce procédé et un procédé pour la préparation d'hydrocarbures consistant à mettre en contact un mélange de monoxyde de carbone et d'hydrogène avec le catalyseur précité.
