摘要
用程序升温（ＴＰＲ、ＴＰＯ）和活性评价等方法研究助剂（ＭｇＯ，ＣａＯ，Ｌａ２Ｏ３和Ｃｅ２Ｏ３）对ＣＯ２／ＣＨ４重整制合成气Ｎｉ基催化剂性能的影响。结果表明ＭｇＯ和Ｃｅ２Ｏ３能较多地提高ＣＨ４和ＣＯ２的转化率。
Efffect of promoters
(MgO,CaO,La2O3 and Ce2O3)to Nibased catalysts for CO2 reforming of methane to syngas was
studied by temperature programmed technique (TPR,TPO) and test of catalytic performance. The
results showed that MgO and Ce2O3 were more effective for conversion of CH4 and CO2.The
Ce2O3 was the best promoter to suppress carbon deposition.
