Abstract
Abstract The catalyst comprises a Group VIII noble metal, mordenite having a silica-to-alumina ratio of at least 19:1, and an adsorbent refractory inorganic oxide. The preferred Group VIII noble metal is platinum; the preferred refractory inorganic oxide is a catalytically active alumina. The mordenite has a silica-to-alumina ratio of less than 45:1. The processes in which the catalyst is employed are processes for the reforming of petroleum hydrocarbon feedstocks.
