Abstract
A multimetallic catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, a nickel component, a Group IV-A metallic 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 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, an iridium component, a nickel component, a germanium component, and a chloride component with an alumina carrier material.
Claims13
A process for reforming a gasoline fraction which comprises contacting said fraction in the presence of hydrogen at reforming conditions with a catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 weight percent platinum or palladium, about 0.01 to about 2 weight percent iridium, about 0.01 to about 5 weight percent nickel, about 0.01 to about 5 weight percent of a Group IV-A metal, and about 0.1 to about 3.5 weight percent halogen, wherein the platinum or palladium, iridium, nickel, and Group IV-A metal are uniformly dispersed throughout the porous carrier material, wherein substantially all of the platinum or palladium, iridium, and nickel are present in the corresponding elemental metallic states, and wherein substantially all of the Group IV-A metal is present in an oxidation state above that of the corresponding elemental metal.
