The present invention is a method of hydrogenation using a catalyst in the form of a plurality of porous particles wherein each particle is a support having nickel metal catalytic phase or reduced nickel deposited thereon in a first dispersed phase and an additional ruthenium metal deposited onto the support in a second dispersed phase. The additional ruthenium metal is effective in retarding or reducing agglomeration or sintering of the nickel metal catalytic phase thereby increasing the life time of the catalyst during hydrogenation reactions.
Procédé d'hydrogénation à catalyseur sous forme d'une pluralité de particules poreuses, chaque particule constituant un support à phase catalytique à base de nickel ou à dépôt de nickel réduit sur le support dans une première phase dispersée et à dépôt de ruthénium additionnel sur le support dans une seconde phase dispersée. Le ruthénium additionnel agit efficacement pour retarder ou réduire l'agglomération ou le frittage de la phase catalytique au nickel, ce qui augmente la durée de vie du catalyseur pendant les réactions d'hydrogénation.
