Research progress of catalysts for hydrogenation of benzene
The classification of benzene hydrogenation catalysts is introduced. The research progress and production process of homogeneous catalysts,heterogeneous catalysts and ionic liquid catalysts are summarized,and the heterogeneous catalysts can be used in liquid phase and gas phase hydrogenation of benzene. The methods for evaluating and analyzing the catalysts are reviewed,and the hydrogenation mechanism is discussed. The adsorption way on the surface of catalyst,controlling of reaction rate,adsorption form of benzene and hydrogen are illustrated.
