烟气中氮氧化物污染的治理

对最新的一些烟气NOx脱除技术进行了综述，对于主要的两种燃烧后烟气NOx脱除工艺技术─选择性催化还原（SCR）及选择性非催化还原（SNCR）进行了较为详细的讨论，并对这两种方法的优缺点进行了对比．还对其它的一些工艺技术如碳氢化合物选择性催化还原（HC—SCR）及NOx直接催化分解作了简要介绍．

Pollution Control of NO_x in Smoke

An overview of recent NOx reduction technologies have been given in this paper, two major NOx reduction technologies include selective catalytic reduction(SCR )and selective non catalytic reduction (SNOR)have been discussed in detail,their advantages as well as disadvantages have been compared with each other. Other technologies, such as hydrocarbon─ selective Catalytic reduction(HC-SCR)and direct catalytic decomposition of NOx have been introduced briefly.
