Abstract
A novel catalytic composite and a process for its use is disclosed. The catalyst composite comprises a first component selected from Group IA and Group IIA elements of the Periodic Table of the Elements, a second component selected from iridium, and osmium, or mixtures thereof, a third component selected from the elements of Group IVA of the Periodic Table of the Elements, platinum, and a support having a nominal dimension (d) of from 50 to 10,000 microns. The catalytic composite is characterized in that both the second component and platinum are surface-impregnated upon the support, with the concentration gradient of the second component being steeper than that of platinum. The second component is eggshell surface-impregnated.
