Abstract:
Copper sorbents which are resistant to the reduction by hydrogen are used as a guard bed for an acetylene conversion zone. The adsorbents include cuprous oxide, cupric oxide, copper metal, and a halide and are pre-reduced prior to be loaded into the guard bed. The sorbents can remove contaminants that would poison selective hydrogenation catalysts used for a selectively hydrogenating acetylenic compounds in an olefin stream. The sorbents may also selectively hydrogenate the acetylenic compounds.

Claim (Index 16):
A process for removing contaminants from a stream, the process comprising:\n forming a sorbent from a mixture of a support material, a basic copper carbonate, and a halide material; calcined and activating the sorbent at a temperature of no more than 160\u00b0 C.; loading the sorbent into a contaminant removal zone after the sorbent has been calcined and activated; passing an olefins stream to the contaminant removal zone, the olefin stream comprising olefins and one or more contaminants selected from the group consisting of mercury, arsenic, phosphine and sulfur compounds from the olefins stream; removing at least one of the one or more contaminants from the olefin stream with the sorbent; and, selectively converting acetylenic compounds from the olefin stream to olefins in the presence of hydrogen.
