ABSTRACT:
Isomerizable hydrocarbons including paraffins, cycloparaffins, olefins and alkyl aromatics are isomerized by contacting the hydrocarbon at isomerization conditions with a catalytic composite comprising a platinum group metal on an alpha-alumina monohydrate support wherein said support is prepared by admixing an alpha-alumina monohydrate with an aqueous ammoniacal solution having a pH of at least about 7.5 to form a stable suspension and commingling said suspension with a salt of a strong acid to form an extrudable paste or dough. Upon extrusion, the extrudate is dried and calcined to form said alumina support.
