| Abstract: | The Cu-Cr/SiO_2 catalyst were prepared by sol-gel technique.The catalysts were applied for selective hydrogenation of furfural to 2-methylfuran.The influences of Cu/Cr value,temperature and H_2/FFA value on catalytic performance of catalyst were discussed in a gradientless reactor.X-ray diffraction(XRD) was used to characterize the catalyst.It was found that the catalytic activity of the catalyst is directly related to the ultrafine copper crystal. |
