ABSTRACT:
A catalyst having dual functionality for the removal of arsenic and the selective hydrogenation of diolefins from monoolefin-containing hydrocarbon streams that have an arsenic concentration and a diolefin concentration, and processes for making and using such catalyst. The catalyst is a heat treated shaped mixture of a refractory oxide and a Group VIII metal that is overlaid with additional Group VIII metal.
