Abstract
Steam reforming catalysts which are suitable for the gasification of hydrocarbons, particularly heavier hydrocarbons such as kerosene 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 characterized in that they have a pore size distribution such that at least 55% by volume of the pores of the calcined but unreduced catalyst which have a pore radius of 12-120A is in the range 12-30A. The catalysts are produced by coprecipitation, preferably at temperatures of not more than 60.degree. C., by 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, e.g., for the production of substitute natural gas.
