中文摘要：
以十六烷基三甲基溴化铵（CTAB）为模板剂，用共沉淀-水热法制备了CH4/CO2重整制取合成气催化剂Ce-Zr-Co-Ox复合氧化物，并用XRD、SEM和H2-TPR对其进行了表征,同时考察了Ce、Zr、Co元素含量，催化反应温度，CTAB添加量以及空速对反应的影响。结果表明，增加Co含量可提高Ce-Zr-Co-Ox的催化活性，当n（Ce）：n（Zr）：n（Co）为3：3：5时，其催化活性较好，但容易烧结，而在制备过程中适当添加CTAB模板剂可改善催化剂的抗烧结性能，提高其稳定性，当n（CTAB）/n（Ce＋Zr＋Co）为1时，催化剂活性及稳定性较好。
英文摘要：
Ce-Zr-Co-Ox composite oxide catalysts were prepared by the co-precipitation-hydrothermal method using cetyltrimethy- lammonium bromide （CTAB） as the template and characterized by XRD, SEM and H2-TPR. The effects of the addition of CTAB, the contents of Ce, Zr and Co elements, reaction temperature and space velocity on the carbon dioxide reforming of methane to syngas over the catalysts were investigated. The results showed that the catalytic activity would increase with the increase of the Co content in the catalysts; the catalyst with the Ce/Zr/Co mole ratio of 3/3/5 showed the highest activity but was easily sintered; the addition of CTAB in the process of catalyst preparation could improve the sintering resistance of the catalysts; and the catalyst prepared using the CTAB/（Ce＋Zr＋Co） mole ratio of 1 exhibited optimum catalytic activity and stability.
