Abstract
Abstract Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a bimetallic acidic catalyst comprising a combination of catalytically effective amounts of a platinum or palladium component, a ruthenium component and a halogen component with a porous carrier material. The components are present in the bimetallic catalyst in amounts, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum or palladium, about 0.01 to about 2 wt. % ruthenium and about 0.1 to about 3.5 wt. % halogen. Moreover, the platinum or palladium component and the ruthenium component are uniformly dispersed throughout the porous carrier material and substantially all of the platinum or palladium component and the ruthenium component are present in the corresponding elemental metallic states while substantially all of the halogen component is present in the form of the combined halide. A specific example of the hydrocarbon conversion process disclosed is a process for reforming a gasoline fraction wherein the gasoline fraction and hydrogen are contacted with the disclosed bimetallic catalyst at reforming conditions. Also disclosed in a trimetallic catalyst comprising a combination of a Group IVA metallic component with the bimetallic catalyst.
