Copper-supported catalysts in methanol synthesis and water gas shift reaction

The comparative studies of physicochemical properties of Cu-support catalysts (support = ZnO, Al 2 O 3 , Cr 2 O 3 , ZnAl 2 O 4 , FeAlO 3 , or CrAl 3 O 6 ) and their catalytic activity in methanol synthesis and water gas shift reaction were the main goal of this work. The promotion effect of copper addition in both reaction was proved. The formation of spinel type structure CuCr 2 O 4 , ZnAl 2 O 4 and binary oxide CrAl 3 O 6 , FeAlO 3 during calcination process was confirmed by XRD technique. Results showed that 20% Cu/FeAlO 3 had the best performance in water gas shift reaction. The best selective and active catalyst in methanol synthesis was 20% Cu/ZnAl 2 O 4 .
