  • the precious metal element may be Pt, Pd, Ru, Rh; preferably it is ruthenium.
  • Q is the precious metal element x is from about 1 to about 4 2 y is from about 0.05 to about 1.5 n is about 4
  • the preformed carrier is preferably a preformed porous ceramic body adapted to hold the catalyst in the pores and optionally on the exterior too.
  • the preformed porous ceramic body may be alumina, stabilised alumina, zirconia, spinel, aluminosilicates, silica, and the like.

  • the precious metal component will be provided by a decomposable salt of one of the following precious metals: Pt, Pd, Ru, Rh.
  • the preferred precious metal component is a thermally decomposable salt of ruthenium.
  • the invention provides a method which comprises first forming a catalyst precursor by co-precipitating nickel, aluminium, lanthanum and the precious metal from a solution of their salts, e.g. nitrates, the pH and temperature of the solution being kept substantially constant throughout the reaction so that the precursor formed comprises a layer structure and the approximate chemical composition:
  • the catalyst composition may be utilised either in a form in which it is held within a porous ceramic matrix or as an apparently homogenous material, the form being chosen according to need.
  • the preformed porous ceramic body is impregnated, preferably under vacuum, with a solution containing salts of nickel, lanthanum, aluminium and the precious metal, e.g. the nitrates, with a precipitation agent such as urea.

  • the catalyst is then dried by heating to a suitably elevated temperature.
  • the precious metal component may also be added by post impregnation).
  • the metal loading of the catalyst may be increased by repetition of the process steps. Prior to re-impregnation of the catalyst the pores must be opened. The process the pores may be opened by thermal decomposition of material within the pores. Alternatively the catalyst is washed with water or weak alkaline solution and then dried at a suitable elevated temperature. The catalyst of the required metal loading is subjected to a final calcination temperature of about 450°C.
  • the final composition in the ceramic pores has the preferable approximate range of about 5-30 wt. %, Ni, about 0.1 - about 15 wt. % La and about 0.1 - about 2% Ru. It is preferred that the atomic ratios of Ni:AI in the active material are about 1.5 to about 4:1. 4 Promoters/spacers such as zirconium may be added, preferably as the nitrate, to further increase the stability and/or improve the selectivity of the catalyst.

  • the catalyst composition of the invention will have enhanced thermal stability and carbon gasification activity.
  • the nickel catalyst composition may be used for example in the high temperature steam reforming of hydrocarbons.
  • Other possible applications include the methanation of gases containing high concentration of carbon oxide particularly arising from coal gasification processes.

  • Sample B was prepared by adding 0.2% ruthenium to the nickel, lanthanum and aluminium coprecipitated in the alpha alumina carrier in the manner of our EP 0044117B.
  • Sample C was prepared by post-impregnating the alpha alumina carrier with 0.2% ruthenium, already impregnated with nickel lanthanum aluminium in the manner of our EP
