ABSTRACT Steam reforming catalysts which are suitable for the gasification of hydrocarbons, particularly heavier hydrocarbons such as kerosine and gas oils consist of calcined and reduced forms of a basic mixed carbonate of nickel, aluminium and chromium produced by coprecipitation The catalysts are further characterised in that they have a pore size distribution such that at least 55% by volume of the pores of the calcined but unreduced catalys? which have a pore radius of 12-120.ANG. is in the range 12-30.ANG.. The catalysts are produced by coprecipitation, preferably at temperatures of not more than 60°C, using an alkali carbonate as the precipitant and by adding the precipitant to a mixed solution of alumium, nickel and chromium III compounds. The catalysts which have good sinter and polymer resistance may be used for the production of methane-containing gases, eg fro the production of substitute natural gas.
