富氧条件下氢气低温选择催化还原NO_x反应机理研究

Research on NOx reaction mechanism of low temperature selective catalytic reduction with hydrogen under rich oxygen condition

煤燃烧中产生的氮氧化物(NOx)是不可忽视的大气污染源,论文总结了近年来在富氧条件下采用H2选择催化剂还原(H2-SCR)消除NOx的反应机理,重点对H2-SCR反应历程中NOx的存在形式将反应机理进行了分类和总结。

The NOx from the coal combustion is the unignorable air pollution sopurce. The paper summarized the reaction mechanism of H2 elective catalytic reduction （ H2 - SCR） to eliminate NOx under the rich oxygen conditions. The paper classified and summarized the reaction mechanism of the NOx in the H2 - SCH reaction processing.
