Abstract
A method of regenerating a contaminant metal-containing, coke deactivated, molecular sieve-free catalyst having at least one hydrogenation metal and at least one Group IV metal deposited on an inorganic oxide support comprising contacting the catalyst with an oxygen-containing gas under conditions sufficient to remove a substantial amount of the coke from the catalyst.
