Abstract
A novel trimetallic catalytic composite, a method of manufacture and process use thereof is dislcosed. The composite comprises a refractory support having a nominal diameter of at least 650 microns and having deposited thereon a uniformly dispersed platinum component, a uniformly dispersed Group IVA metal component and a surface-impregnated metal component selected from the group consisting of rhodium, ruthenium, cobalt, nickel, or iridium. When this catalytic composite is used in the reforming of hydrocarbons at low pressures, significant improvements in activity stability is observed compared to catalysts of the prior art.

A catalytic composite for the conversion of hydrocarbons comprising a uniformly dispersed platinum component, a uniformly dispersed Group IVA metal component, a surface-impregnated metal component selected from the group consisting of rhodium, ruthenium, cobalt, nickel and iridium and a halogen component on a refractory support having a uniform composition and a nominal diameter of at least 650 microns.
A method of preparing a catalytic composite comprising compositing a platinum component, a Group IVA metal component, a metal component selected from the group consisting of rhodium, ruthenium, cobalt, nickel and iridium and a halogen component on a refractory support having a uniform composition and a nominal diameter of at least 650 microns such that the platinum and tin components are uniformly dispersed and said metal component is surface-impregnated onto said refractory support.
