An improved reforming process utilizing a novel trimetallic catalytic composite is disclosed. 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 rhdoium, ruthenium, cobalt, nickel, or iridium. When this catalytic composite is used in the reforming of hydrocarbons at low pressures, significant improvements in activity and stability are observed compared to catalysts of the prior art. |
