A Group VIII metal and chloride-containing composition (effective as an alkane/cycloalkane isomerization catalyst) is prepared by a method which comprises mixing aluminum trichloride with a solid material containing at least one Group VIII metal (Pt and/or Pd and/or Ni) and alumina, heating the obtained mixture in an inert gas at about 450-750°C, and then treating the mixture with a hydrogen chloride-containing gas at about 300-700°C.

Une composition renfermant un chlorure et un métal du Groupe VIII (efficace comme catalyseur d'isomérisation d'alcanes ou de cycloalcanes) est préparée par une méthode consistant à mélanger du trichlorure d'aluminium avec un matériau solide renfermant au moins un métal du Groupe VIII - Pt et (ou) Pd et (ou) Ni - et de l'alumine, à chauffer le mélange obtenu dans un gaz inerte à environ 450-750 degrés C, et enfin à traiter le mélange avec un gaz contenant du chlorure d'hydrogène, à environ 300-700 degrés C.
