Catalysts are made by subjecting a metal loaded "ammonium" zeolite, which has been manufactured by contacting zeolitic material with a n monia and/or ammonium ions and which has been composited with one or more hydrogenative metals, to a controlled oxidative calcination employing oxygen or oxygencontaining gas, the controlled calcination comprising heating at above 200‹ C. to remove ammonia and thereafter heating at a higher temperature. The zeolite may be mordenite and the hydrogenative metals may be Pt or Pd. In addition to NH 4 + "ammonium" means H 2 N.NH 2 , H2 N. OH, N-alkyl ammonium compounds e.g. tetra-methyl or ethyl ammonium hydroxide. Additionally the catalysts may contain a conventional clay and the products may be shaped into cylindrical particles.
