一般浸渍法与真空浸渍法的比较说明，真空浸渍制备的催化剂，其表面具有较多的Ｎｉ原子，催化活性较高．现场ＴＰＯ实验表明，ＣＯ岐化的积炭量大于ＣＨ４解离的积炭量．从而提出镍基催化剂的积炭主要来自反应生成气ＣＯ的岐化
The comparison of general impregnation method and vacuum impregnation method shows that the catalyst prepared by vacuum impregnation has more Ni atoms on the surface and higher catalytic activity. The on-site TPO experiments show that the carbon deposition of CO is greater than that of CH4 dissociation. Therefore, it is proposed that the carbon deposition of Ni-based catalysts mainly comes from the disproportionation of CO in the reaction gas
