Abstract
A novel hydrocarbon conversion process for the reforming of naphtha charge stocks containing less than 50 wt. ppm water is disclosed. The process utilizes a catalytic composite comprising 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 low water level hydrocarbons at low pressures significant improvements in activity stability is observed compared to catalysts of the prior art.
