Abstract: front page image
(EN)A process for preparing a cobalt based Fischer-Tropsch synthesis catalyst precursor includes introducing a multi-functional carboxylic acid having the general formula (1 ) HOOC -C*R1C*R2- COOH (1 ) or a precursor thereof, where C* in each of C*Ri and C*R2 is a sp2 carbon, and R1 and R2 are the same or different, and are each selected from the group consisting of hydrogen and an organic group, into and/or onto a particulate catalyst support. The ratio of the quantity of multi¬ functional carboxylic acid used relative to the support surface area is at least 0.3 μmol carboxylic acid/m2 of support surface area. Simultaneously with the introduction of the carboxylic acid into and/or onto the catalyst support, or subsequent thereto, a cobalt compound is introduced into and/or onto the catalyst support. The impregnated support is calcined to obtain the cobalt based Fischer-Tropsch synthesis catalyst precursor.
(FR)L'invention concerne un procédé de préparation d'un précurseur de catalyseur de synthèse de Fischer-Tropsch à base de cobalt, qui comprend l'introduction d'un acide carboxylique multifonctionnel représenté par la formule générale (1) HOOC -C*R1C*R2- COOH (1 ) ou l'un de ses précurseurs, dans laquelle C* dans chacun des groupes C*Ri et C*R2 représente un atome de carbone sp2, et R1 et R2 sont identiques ou différents et sont chacun sélectionnés dans l'ensemble consistant en un atome d'hydrogène et un groupe organique, dans et/ou sur un support de catalyseur particulaire. Le rapport de la quantité d'acide carboxylique multifonctionnel utilisé à la surface du support est au moins égal à 0,3 μmol d'acide carboxylique/m2 de surface de support. Simultanément à l'introduction de l'acide carboxylique dans et/ou sur le support catalytique, ou après celle-ci, un composé de cobalt est introduit dans et/ou sur le support de catalyseur. Le support imprégné est calciné afin d'obtenir le précurseur de catalyseur de synthèse de Fischer-Tropsch à base de cobalt.
