Pd/C and Raney Ni catalysts were prepared. The structures and performances were characterized by XRD, BET and SEM. The catalytic activity of Pd/C and Raney Ni catalysts were compared by the reaction of hydrogenation of furan to tetrahydrofuran. The effects of reaction temperature, hydrogen pressure and amount of catalyst on conversion and selectivity were investigated. The results showed that the catalytic activity of Raney Ni was better than that of Pd/C.
