| 摘 要： | 用脉冲微反应系统研究了１０２３Ｋ下，ＣＯ２在Ｎｉ／Ａｌ２Ｏ３上的裂解及其与ＣＨ４的反应，发现ＣＯ２裂解吸附产生Ｏ（ａｄ）和ＣＯ，该反应步骤较慢。产生的ＣＯ会进一步在Ｎｉ表面裂解，而由ＣＨ４裂解产生的活性碳物种与Ｏ（ａｄ）的反应是一较快步骤。

| Abstract: | The dissociation of CO 2 and its reaction with CH 4 have been investigated at 1023 K over Ni/Al 2O 3 using pulsed-flow micro-reactor. It was found that dissociative adsorption of CO 2 occurred to give O(ad) and CO, which was a slow step. The formed CO would be further dissociated on Ni catalyst. The active carbon species would be inactivated quickly and its reaction with O (ad) was a fast step. |
