Heterogeneous catalysts of hydrogenation

The main types of heterogeneous catalysts used for hydrogenation, the methods for their preparation, structure and chemistry of their surface are considered, as well as catalytic activity and the mechanism of action in the hydrogenation of unsaturated and aromatic compounds, CO, carbonyl compounds and in hydrorefinement of fuels. The primary attention is paid to supported Ni catalysts, the methods for their preparation, physico-chemical studies and the development of novel catalytic systems via modification. A novel type of catalysts for hydrogenation, metal carbides, is described. Some aspects of mechanochemical treatment of hydrogenation catalysts, including in situ methods, are discussed. Sulfide catalysts of hydrorefinement are also described in detail.
