以ＭｇＯ、Ａｌ２Ｏ３以及其混合物为载体，研究ＭｇＯ／Ａｌ２Ｏ３ｍｏｌ比对ＣＨ４／ＣＯ２重整Ｎｉ基催化剂性能的影响．结果表明ＭｇＯ／Ａｌ２Ｏ３＝２（ｍｏｌ比）时其催化性能最好，积炭量最少．现场ＴＰＯ实验表明ＣＯ岐化的积炭量均大于相应催化剂ＣＨ４解离的积炭量，表明ＣＨ４／ＣＯ２重整Ｎｉ基催化剂的积炭，ＣＯ歧化高于ＣＨ４解离 The effect of MgO / Al2O3 molar ratio on the performance of Ni-based catalysts for CH4 / CO2 reforming was studied using MgO, Al2O3 and their mixtures as carriers. The results show that MgO / Al2O3 = 2 (mol ratio), the best catalytic performance, the least amount of carbon deposition. On-site TPO experiments show that the carbon deposition of CO is greater than that of the corresponding catalyst CH4 dissociation, indicating that the CH 4 / CO 2 reforming Ni-based catalyst coke, CO disproportionation higher than CH 4 dissociation
