| Abstract: | MgO, Al 2O 3 and MgO/Al 2O 3 mixtures were used as support and the effect of the mole ratio of MgO/Al 2O 3 on catalytic performance of Ni based catalysts for CH 4/CO 2 reforming has been studied. The result indicates that the catalyst with support of MgO/Al 2O 3=2 has the best performance and the least carbon deposits on the catalyst. The in situ TPO experiments show that the carbon deposits from CO disproportionation were always more than that from CH 4 dissociation for the same catalyst. This implies that the carbon deposit on the catalysts in CO 2 reforming of methane reaction came from the CO disproportionation more. |
