Abstract
A catalyst for production of high octane number gasoline having low aromatic content from a hydrocarbon feedstock containing n-paraffins includes a zeolite composition containing chromium in an amount of between about 0.1% to about 1.0% by weight of the catalyst, said chromium being located at acidic sites of said zeolite composition whereby aromatic forming reactions are inhibited. The catalyst is provided according to a process including sequential impregnation so as to position chromium at the acidic sites as desired.
