Patent

CA 2407110

A catalyst or precursor thereto comprising cobalt and/or a cobalt compound on a transition alumina support having a total cobalt content of at least 41% by weight and a cobalt surface area, after reduction, greater than 25 m2 per gram of total cobalt. The catalyst or precursor may be made by slurrying a transition alumina powder having a pore volume of at least 0.7 ml/g with an aqueous cobalt ammine carbonate complex and heating the slurry to decompose the complex.

L'invention concerne un catalyseur ou un précurseur de celui-ci, comprenant du cobalt et un composé de cobalt sur un support d'alumine de transition présentant une teneur totale en cobalt d'au moins 41 % en poids et une surface de cobalt, après réduction, supérieure à 25 m<2> par gramme de cobalt au total. On peut fabriquer le catalyseur ou le précurseur de l'invention en formant une suspension à partir d'une poudre d'alumine de transition possédant un volume de pore d'au moins 0,7 ml/g et d'un complexe ammine cobalt aqueux, et par chauffage de ladite suspension, de manière que ledit complexe soit décomposé.
