Abstract:
A catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, and a Group IVA metallic component with a carrier material containing alumina and a finely divided, zeolitic crystalline aluminosilicate, is disclosed. A specific example of the catalytic composite disclosed herein is a composite containing 0.01 to 2 wt. % platinum or palladium, 0.01 to 2 wt. % iridium and 0.01 to 5 wt. % germanium, tin or lead combined with a gamma-alumina carrier material having 0.1 to 20 wt. % of the hydrogen form of mordenite uniformly distributed therethrough. Principal utility of these catalytic composites is, broadly, in processes for the conversion of hydrocarbons and, more particularly, in a process for the production of LPG and a high octane reformate.

Abstract:
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a bimetallic acidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, an indium component and a halogen component with a porous carrier material. The platinum group component and halogen component are present in the bimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. percent platinum group metal and about 0.1 to about 3.5 wt. percent halogen. The indium component is present in amounts corresponding to an atomic ratio of indium to platinum group metal of about 0.1:1 to about 1:1. Moreover, the platinum group and indium components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group component is present therein in the corresponding elemental metallic state while substantially all of the indium component is present therein in an oxidation state above that of the corresponding metal. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and hydrogen stream are contacted with the novel acidic bimetallic catalyst disclosed herein at reforming conditions. Also disclosed is a novel trimetallic catalyst comprising a combination of a Group IVA metallic component with the acidic bimetallic catalyst.
