Abstract
A catalyst for selective hydrogenation of hydrocarbons is presented. The catalyst selectively hydrogenates acetylenes and diolefins to increase the monoolefins in a product stream. The catalyst includes a layered structure with an inert inner core and an outer layer bonded to the inner core, where the outer layer is a metal oxide and has at least two metals deposited on the outer layer.
