Abstract
Abstract A multimetallic acidic catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, a rhodium component, a nickel component and a halogen component with a porous carrier material is disclosed. Preferred modifying components for the disclosed catalytic composite are a sulfur component and/or a Group IVA metallic component. The principal utility of this composite is in the conversion of hydrocarbons, particularly in the reforming of a gasoline fraction to make a high octane reformate. A specific example of the disclosed catalytic composite is a combination of catalytically effective amounts of a platinum component, a rhodium component, a nickel component and a chloride component with an alumina carrier material.
