用甲烷选择性催化还原一氧化氮

Catalytic Selective Reduction of NO with Methane

废气中的NO的排放已经引起人们的日益关注 .甲烷是天然气中的主要成分 ,来源丰富 ,使用方便 ,作为NO的还原剂极具潜力 .讨论了用甲烷催化还原NO的各种催化剂的相对活性 ,及影响催化效率的各种因素 。

The removal of nitrogen oxides from exhaust gases is concerned by more and more people. Various approaches have been developed depending on the application. Methane, the main component of natural gas, being readily available and easy to use, has most potential as NO reductant. A number of materials which had been reported to be catalysts for this catalytic reduction of NO were reviewed, including direct comparison regarding the relative activity and catalyst effective factors. The reaction mechanism has been explored preliminarily.
