ABSTRACT:
A nickel containing catalyst composition of high thermal stability and outstanding resistence to carbon deposition is provided for use in the steam reforming of hydrocarbons. The catalyst is derived from a precursor having lanthanum ions incorporated into a layer structure by means of coprecipitation from a solution containing soluble salts of the catalytically active components. The precursor is of approximate chemical composition Ni.sub.6 Al.sub.x La.sub.y (CO.sub.3).sub.x+y /2(OH).sub.12+2(x+y) nH.sub.2 O. A range of atomic ratios for the component is disclosed. Additional embodiments of the precursor are disclosed wherein anions other than carbonate are present and various proportions of the nickel content are replaced by magnesium.
