ABSTRACT:
An improved process for the catalytic dehydrogenation of paraffinic hydrocarbons is disclosed. Feed paraffinic hydrocarbons are dehydrogenated to yield an olefin-containing vapor stream, which is partially condensed to produce a liquid phase process stream which contains by-product diolefins along with the intended product monoolefins. The liquid phase process stream and added hydrogen are passed through a selective hydrogenation zone in which diolefins are catalytically converted to monoolefins. This increases the quality of the product monoolefin stream. The selective hydrogenation zone is located between the vapor-liquid separator and stripper column of the dehydrogenation zone.
