Title: Modification of the Cu-Zn catalysts supporred on γ-Al_2O_3 for hydrogenation of furfural to furfuryl alcohol
Abstract: Co-modified Cu-Zn catalysts supported on Al2O3 were prepared by impregnation method.The influence of Cu-Zn content,Co content and reaction temperature on the catalytic behaviors was investigated.The results showed that the selectivity to furfuryl alcohol of 100%,furfural conversion of 94.6% were attained,11% higher than the conversion over unmodified Cu-Zn/γ-Al2O3 catalyst,under the following condition: n(Cu)∶n(Zn)∶n(Al)∶n(Co)=1.0∶2.0∶3.0∶0.51,413 K,flow rate of hydrogen 0.5 mL·s-1,LHSV of furfural2 h-1.
