METHOD FOR SELECTIVE HYDROGENATION OF PHENYLACETYLENE IN THE PRESENCE OF STYRENE

Title:

METHOD FOR SELECTIVE HYDROGENATION OF PHENYLACETYLENE IN THE PRESENCE OF STYRENE

Document Type and Number:

WIPO Patent Application WO/2010/069144

Kind Code:

A1

Abstract:

A method for selective hydrogenation of phenyl acetylene in the presence of styrene is provided. Said method involves using hydrocarbon fraction containing phenyl acetylene and styrene as raw materials. The raw materials are contacted with the catalyst containing 0.02-8wt% of carbon, a certain amount of active component Ni and/or Pd, and the carrier selected from magnesium oxide, silica, alumina and molecular sieve in the hydrogenation conditions. Said carbon is formed on the catalyst surface by pre-coking. The phenyl acetylene of reaction effluent is hydrogenated into styrene.
