ABSTRACT:
A gasoline fraction is catalytically reformed by contacting the gasoline fraction and a hydrogen stream at reforming conditions with an activated bimetallic acidic catalytic composite comprising a combination of a platinum group component, a tin component and a halogen component with a porous carrier material, the catalytic composite having been activated by contacting same with an activating gas comprising oxygen and a halogenating component selected from the group consisting of halogen and hydrogen halide at a temperature between 700.degree. and 1100.degree. F. for a time of at least 0.5 to about 10 hours. Also disclosed is a process for activating a catalytic composite containing platinum in the form of platinum, platinum oxide or platinum sulfide, tin in the form of tin oxide or tin sulfide and halide in combination with a porous alumina carrier material, which process comprises contacting the catalytic composite with an activating gas comprising oxygen and a halogenating component selected from the group consisting of halogen and hydrogen halide at a temperature of about 700.degree. to 1100.degree. F. for a time of at least about 0.5 to about 10 hours.
