The present invention is 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 metal deposited onto the support in a second dispersed phase. The additional metal, which is selected among copper, tin, rhenium and silver, is effective in retarding or reducing agglomeration or sintering of the nickel metal catalytic phase without substantially affecting the catalytic activity, thereby increasing the life time of the catalyst.
Catalyseur sous forme de plusieurs particules poreuses, chacune étant un support à phase catalytique à base de nickel ou à dépôt de nickel réduit dans une première phase dispersée, avec dépôt de métal additionnel sur le support dans une seconde phase dispersée. Le métal additionnel (cuivre, étain, rhénium ou argent) agit efficacement pour retarder ou diminuer l'agglomération ou le frittage de la phase catalytique à base de nickel, sans affecter sensiblement l'activité catalytique, ce qui augmente la durée de vie du catalyseur.
