摘　　要：用离子交换法制备Co SZM 5催化剂,考察有氧条件下,在甲烷选择还原NO的反应中,高 压脉冲等离子体的加入对Co SZM 5活性的影响.发现在一定温度范围内,高压脉冲等离子体与 Co SZM 5之间存在协同效应,针对这个问题,初步探讨了高压脉冲等离子体活化CH4催化还原 净化NO的反应机理.The effect of the high voltage pulse discharge plasma on the catalytic activity of Co-ZSM-5 catalyst for the selective catalytic reduction of NO to N 2 by CH 4 in the presence of excess oxygen has been investigated.We found that a cooperative effect between the high voltage pulse discharge plasma and Co-ZSM-5 catalyst is existed within the scope of certain temperature;and based on which the reaction mechanism of the catalytic reduction of NO with CH 4 activated by the high voltage Pulse discharge plasma has been explored preliminarily.
