中文摘要：
在流化床中评价了用于甲烷二氧化碳氧化重整制合成气反应的Ni—Al2O3／SiO2催化剂体系（NixAlSi，x代表Al的质量分数，Ni的质量分数为4％）的催化性能．利用XRD，CO2（O2）-TPD，积炭量测定等手段对催化剂进行了表征．结果表明，Al2O3的添加促进了Ni金属的分散；增强了对CO2和O2的吸附能力，使催化剂的抗积炭性能得到很大的提高，延缓了催化剂的失活．
英文摘要：
The production of syngas from reforming of methane with CO2 and O2 was tested on Ni-Al2O3/SiO2 catalysts which was designated as NixAlSi （the x symbol was the weight percent of Al, and the weight percent of Ni was 4 %） in a fluidized-bed reactor. The catalysts of NixAlSi were characterized by XRD,CO2（O2）-TPD and TG. It was demonstrated that the addition of Al2O3 significantly delayed the deactivation of Ni/SiO2 catalyst and drastically enhanced the ability of anti-carbon deposition, which was attributed to the improving of adsorption ability of CO2 and O2.
