| 中文摘要: |
| 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。 |
| 英文摘要: |
| Vacuum impregnation method was better than the common impregnation method, because the catalyst has more Ni on the surface and higher catalytic activity. Temperatureprogrammed oxidation (TPO) experiments showed that carbon deposition of CO disproportionation is more than that of CH4 decomposition. Therefore it was suggested that carbon deposition of Nibased catalysts for CO2 reforming of CH4 mainly comes from disproportionation of CO formed in the reaction. |
