Patent

CA 2503515

The present invention is directed to processes for preparing supported metal catalysts comprising one or more catalytically active metals applied to a porous catalyst support and to processes that use such catalysts. The process requires the formation of an organic complex during the manufacture of the catalyst which after its formation is either partially or fully decomposed before reduction if the metal to form the catalyst. The catalysts have high levels of metal dispersion and uniform distribution of catalytically active metals on the support. The catalysts obtained form the processes are particularly effective in catalysing Fischer-Tropsch reactions and as adsorbants for the removal or organosulfur compounds from hydrocarbons.

La présente invention concerne des procédés de préparation de catalyseurs métalliques sur support, comprenant un ou plusieurs métaux à action catalytique appliqués sur un support catalytique poreux, ainsi que des méthodes d'utilisation de ces catalyseurs. Un des procédés selon l'invention nécessite la formation d'un complexe organique au cours de la fabrication du catalyseur, ce complexe étant partiellement ou totalement décomposé après sa formation avant la réduction du métal pour former le catalyseur. Les catalyseurs selon l'invention possèdent des niveaux élevés de dispersion des métaux et une répartition uniforme des métaux à action catalytique sur le support. Les catalyseurs obtenus par ces procédés sont particulièrement efficaces pour catalyser des réactions de Fischer-Tropsch et en tant qu'adsorbants pour éliminer des composés organosoufrés contenus dans des hydrocarbures.
