Abstract
Abstract A trimetallic acidic catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, a rhodium component, a tin component and a halogen component with a porous carrier material, is disclosed. The principal utility of this composite is in the conversion of hydrocarbons, particularly in the reforming of a gasoline fraction. A specific example of the disclosed catalytic composite is a combination of catalytically effective amounts of a platinum component, a rhodium component, a tin component and a chloride component with an alumina carrier material.
