Abstract
This invention provides a novel base-exchanged shape-selective hydrogenation-dehydrogenation-dehydrocyclization catalyst composition which is a zeolite matrix having a silica-alumina ratio of at least 12, and having a shape-selective functioning intrazeolitic Group VIII metal content between about 0.01-10 weight percent. The zeolite catalyst is adapted for efficient shape-selective metal function hydrogenolysis, dehydrogenation and aromatization conversion of hydrocarbon mixtures, with a minimized acid-catalyzed cracking activity.
