Abstract

The present invention discloses a process for the selective hydrogenation of phenylacetylene in the presence of styrene, comprising contacting a phenylacetylene and styrene-containing hydrocarbon fraction feedstock with a carbon-containing catalyst under hydrogenation reaction conditions, wherein the carbon-containing catalyst has a carbon content of from 0.02 to 8 wt % based on the weight of the catalyst.
