Furfuryl alcohol is an important organic chemical material. The traditional catalysts of furfural hydrogenation to produce furfuryl alcohol contain Cr, which is harmful to people’s health and causes severe environmental pollution. Developing new highly active catalysts in furfuryl alcohol is of great practical significance. The progress of non-chrome catalysts for hydrogenation of furfural to produce furfuryl alcohol has been reviewed. Some environmental-friendly non-chrome catalysts, such as copper catalysts, CuO-CaO/SiO2 catalysts, Cu-Zn-Al catalysts, load Ni and ultra-fine Ni-B amorphous alloy catalysts, had been discussed and their preparations and structure characterizations were described. Some constructive strategies are presented for the research and applications of such catalysts.

Three different kinds of preparation methods were contrasted and studied to furfural hydrogenation catalyst for 2 - methyl furan production.Cu, Cr-based catalysts are prepared by three different methods, and the differences were also studied in the structure of these catalysts and their catalytic properties on furfural hydrogenation reaction. From the XRD patterns of samples prepared by different methods of Cu-Cr/γ-Al2O3, The results show that: the metal particle size is:the ordinary impregnation method > coprecipitation > solvated metal atom impregnation method. From the SEM photographs by samples, distribution uniformity of the catalyst ion surface: ordinary impregnation method > coprecipitation > solvated metal atom impregnation method. The reduction degree of the metal: solvated metal atom impregnation ordinary impregnation coprecipitation method. Furfural hydrogenation experimental results show that the order of catalytic activity is solvated metal atom > general impregnation coprecipitation; the selectivity order of 2 - methyl furan: coprecipitation> ordinary impregnation method solvated metal atom impregnation method.
