摘要
用离子交换法制备Co-ZSM-5催化剂,考察了有氧条件下,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-ZSM-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-ZSM-5之间存在协同效应。在此基础上,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。
In the presence of excess oxygen, effect of high voltage pulse discharge plasma on the catalytic activity of Co-ZSM-5 for reduction of NO by CH_ 4 has been studied. It was found that the coordinated action between high voltage pulse discharge plasma and Co-ZSM-5 existed within a certain range of temperatures; and based on the action mechanism of the reaction was explored.
