| Abstract: | CuO-CaO/SiO 2 catalysts were prepared by sol-gel and impregnation methods The structure of the catalysts was characterized by XRD, TEM and BET,and the catalytic performance of the catalysts was compared with Cu-Cr/Al 2O 3 catalysts The results showed that the sol-gel method could prepare ultrafine particle catalysts The active components had smaller crystal diameter and were more highly dispersed on the support surface ,as compared with the catalysts prepared by impregnation The catalysts had high activity and excellent selectivity in the hydrogenation reaction of furfural As a new type of non-Cr catalysts,they could substitute Cu-Cr catalysts for producing 2-methylfuran |
| Keywords: | copper catalysts preparation methods furfural hydrogenation 2-methylfuran |
