【摘要】 分析研究了催化剂对脉冲放电等离子体作用下，CO2；转化为CO的规律。由于催化剂载体对CO2有一定的吸附能力，在其表面形成CO2富积区；而且催化剂表面为场强加强区，更易发生化学反应，因此催化剂存在时，CO的产生量几乎不受CO2含量的影响；而无催化剂情况下，CO2含量对CO的生成有较大影响。当有O2存在时，有无催化剂情况下，CO生成量都随O2含量的增加而减少，尤其是O2含量从零刚开始增加时；无催化剂情况下CO生成量受O2含量影响较大。更多还原

【Abstract】 The conversion of CO2 to CO in atmosphericpressure with cataiyst by a pulsed discharge plasma hasbeen disscused in this paper. The results show that the con-centration of CO2 has almost no influence on gencration ofCO when catalyst exists; but in contrast, the concentrationof CO2 has larger effect on generation of CO without cata-lyst. With or without catalyse, the concentration of COproduced by pulsed discharge decreases with the increase ofthe concentration of O2. The influence of O2 without cata-lyst is more larger than with catalyst. The explanations ofthe results are based on the absorption of CO2 on the surfaceof catalyst and there is a more intensive electric field on thesurface of catalpst.更多还原
