Abstract
A novel trimetallic catalytic composite, a method of manufacture and process use thereof 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 tin component and a surface-impregnated metal component selected from the group consisting of rhodium, ruthenium, cobalt, nickel, iridium and mixtures thereof. 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.
