ABSTRACT:
Novel compositions, being effective as catalysts for alkane and/or cycloalkane isomerization, are prepared by a method which includes the steps of impregnating alumina with a sulfate of at least one metal selected from the group consisting of copper, iron, cobalt, nickel, manganese, zinc and magnesium, calcining the thus-obtained impregnated alumina materials, and heating the calcined materials with AlCl.sub.3 and at least one chlorinated hydrocarbon (preferably CCl.sub.4) at a temperature of about 40.degree.-90.degree. C. Preferably, this method also includes a step of treating the calcined impregnated alumina materials with gaseous hydrogen chloride before the heating with AlCl.sub.3 and the chlorinated hydrocarbon(s) is carried out.
