摘 要:The catalytic performance of Ni catalysts supported by CeO2-ZrO2 and α-Al2O3 was investigated for methane partial oxidation. Catalysts were measured by XRD. Carbon deposition was analyzed with TG-DTA and Raman. The results show that the activity and stability of catalysts supported on CeO2-ZrO2 are better than those on α-Al2O3. Combined with the characterizations results, the advantage of Ni/CeO2-ZrO2 in catalytic activity can be interpreted by fine Ni dispersion. TG-DTA results illustrate that Ni/CeO2-ZrO2 catalysts exhibit better coking resistance than α-Al2O3 supported catalyst.
