  • Catalytic steam reforming and catalysts therefor
    Patent number: 4104201
    Abstract: A catalyst suitable for steam reforming, especially at low temperatures and high pressures, which is resistant to polymer deactivation, comprises nickel, alumina and ruthenium, optionally together with an oxide, hydroxide or carbonate of an alkali metal or alkaline earth-metal wherein the amount of ruthenium does not exceed 0.8% by weight of the weights of the other components of the catalyst. The nickel and aluminium components of the catalyst are prepared by coprecipitation with the nickel and aluminium components, by impregnation of the precipitated nickel and aluminium components or by physical blending of an insoluble ruthenium compound with the precipitated nickel and aluminium components.
