Abstract
A Group VIII metal- and chloride-containing composition is prepared by a method which comprises mixing (A) a solid material containing at least one Group VIII metal (Pt and/or Pd and/or Ni) and alumina as the support and (B) an alumina-supported aluminum- and chlorine-containing compound which has been prepared by mixing an alumina material with AlCl.sub.3 and/or at least one organoaluminum chloride (such as ethylaluminum dichloride), heating the mixture at a temperature of about 600.degree.-750.degree. C. and then with an HCl-containing gas at a temperature of about 100.degree.-750.degree. C. The thus-obtained composition comprising components (A) and (B) is employed as a catalyst in the isomerization of C.sub.4 -C.sub.8 alkanes and/or cycloalkanes (e.g., n-butane).
