Abstract:
1. A process for selective hydrogenation comprising: absorbing one or more acetylenic compounds in a liquid polar non-hydrocarbon absorbent to provide a reactant stream; providing a hydrogenation catalyst comprising a first metal selected from the group consisting of Group VIII metals and combinations thereof and a second metal selected from the group consisting of Group IB metals, Group IIB metals, Group IIIA metals, Group VIIB metals, and combinations thereof; contacting the reactant stream with the hydrogenation catalyst, in the presence of a gas stream comprising hydrogen and greater than 2000 ppm carbon monoxide, under selective hydrogenation conditions, to provide a product stream; wherein the product stream comprises the ethylenic compounds corresponding to the one or more acetylenic compounds in the reactant stream; and separating the absorbent from the product stream.
