In a process for reforming an olefinic, nitrogen and sulfur containing hydrocarbon feed by contact thereof with a dried, calcined catalyst comprised of from about 0.1 to about 20 percent of a Group VI-B metal component composited with an inorganic oxide support, the improvement comprising contacting and post-treating said dried, calcined catalyst composite with a solution of an alkali or alkaline-earth metal compound, incorporating from about 0.1 percent to about 4 percent of an alkali or alkaline-earth metal substantially entirely upon the surface of said catalyst composite sufficient to neutralize the Bronsted acidity of sid catalyst composite, again drying, and again calcining said neutralized catalyst composite, and then contacting said hydrocarbon feed with said dried, calcined, post-neutralized catalyst composite.
