A HYDROCARBON CONVERSION PROCESS IN WHICH A HYDROCARBON IS CONTACTED AT CONVERSION CONDITIONS WITH A CATALYST CONSISTING ESSENTIALLY OF (1) ALUMINA, (2) A METAL SELECTED FROM THE GROUP CONSISTING OF RUTHENIU, RHODIUM, PALLADIUM AND PLATINUM, AND (3) CHLORINE OR BROMINE WHEREIN AT LEAST A PORTION OF SAID CHLORINE OR BROMINE IS INTRODUCED INTO SAID CATALYST BY CONTACTING A COMPOSITE OF ALUMINA AND SAID METAL AT ELEVATED TEMPERATURE WITH A SELECTED ORGANIC COMPOUND IN THE PRESENCE OF CHLORINE OR BROMINE. THE CATALYST SO PREPARED IS USEFUL IN HYDROCARBON CONVERSION PROCESSES AS ISOMERIZATION, HYDROCRACKING, ALKYLATION, HYDROGENATION AND POLYMERIZATION. |
