Patent

CA 2598883

A method for producing a cobalt on alumina catalyst is disclosed. The catalyst is prepared by thoroughly mixing cobalt nitrate into a peptized alumina slurry, and then spray-drying the slurry to form attrition resistant microspheres. The cobalt prepared by this invention is fully reducible. Optionally, metals such as ruthenium can be added to the cobalt/alumina catalyst by impregnation or methods known in the prior art.

Cette invention a pour objet un procédé de production d~un catalyseur de cobalt sur alumine. Ce catalyseur est préparé en mélangeant soigneusement du nitrate de cobalt dans une bouillie d~alumine peptisée, puis en séchant cette bouillie par atomisation afin de former des microsphères résistantes à l~attrition. Le cobalt préparé selon cette invention est entièrement réductible. Éventuellement, des métaux tels que le ruthénium peuvent être ajoutés aux catalyseurs de cobalt/d~alumine par imprégnation ou par le recours aux procédés utilisés par la technique antérieure.
