The Comparison of Different Preparation Methods of Catalysts for Furfural Hydrogenization to 2-methyl furan
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.
