Abstract
Abstract A novel catalytic composite, a method of making the composite, and use of the composite is disclosed. The novel catalyst comprises a nonacidic zeolite bound within a support matrix. Additionally, the catalyst comprises catalytically effective amounts of a Group VIII metal component. There is also present within the catalyst sufficient surface-deposited alkali metal to provide a surface-deposited alkali metal index of at least 10. The catalytic composite has utility for the conversion of hydrocarbons and, in particular, has specific utility as a dehydrocyclization catalyst.
