Abstract WC catalyst was prepared by temperature-programmed reduction and was oxygen-modified on surface to do line evaluation.Results indicate that under the condition of ��=287 ��,p=2.0 MPa,SV=1.0 h~(-1),n(H_2)/n(n-C_5)=4.0(molar ratio), conversion rate of n-pentane is 64.31%,yield of i-pentane is 61.92%,selectivety of i-pentane is 96.29% and liquid product yield is 97.64%.The catalytic activity of WC is close to that of loaded Pt,and the selectivity of WC is equivalent to that of loaded Pt catalyst.
