The reaction conditions were as follows: reaction pressure 2.0 MPa, mass space velocity 1 .0 h -1, molar ratio of hydrogen to hydrocarbon 3.0, Temperature 2 60 ~ 30 0 ℃ under the conditions. The results show that the Ni-Cu / HM catalyst prepared by the co-impregnation method has excellent n-pentane isomerization activity. SEM analysis shows that the catalyst prepared by the co-impregnation method has higher metal dispersion. At the same time, the effect of the amount of residual sodium and the reaction conditions on the isomerization of n-pentane and the activity stability of the catalyst were also investigated.
