Abstract:

The catalysts for selective hydrogenation of benzene to cyclohexene have been widely used in synthetic fiber industry and other fields. The research status of the catalysts for this reaction is reviewed by focusing on the influence factors on catalytic activity and selectivity，such as active components，supports，promoters，additives and preparation methods. The reaction mechanism of the influence is analyzed and the key to improving cyclohexene selectivity is indicated. The development direction of the catalysts is prospected.
