摘要

Catalyst resistance to carbon deposition in methane reforming with carbon dioxide to produce synthesis gas was studied using fixed-bed pulse reactor chromatography, XRD, TPR and XPS. It was found that the addition of CeO_2 and MgO to Ni/Al_2O_3 catalyst would increase the ability of catalyst resistance to carbon deposition, which might result from the increase in Ni dispersion and in the interaction between N I active site and support.
