摘　　要：The Cu/Cr base catalysts were prepared by impregnation. XRD and TPR technology were applied to characterize the catalysts. The result showed that the Cu/Cr base catalysts performed much better than the conventional Cu/Zn/Al catalysts. The stability of the catalysts was enhanced by promoters such as K, Mg, Ni, Y. But the promoters reduced the initial activity of the catalysts. The promoters except Y improved the selectivity apparently.The Cu/Cr base catalysts were prepared by impregnation.
