分布式燃气内燃机低温脱硝技术现状分析
|
摘要
本文对目前主要的两种低温脱硝技术:低温SCR脱硝技术和低温等离子体脱硝技术进行了较为全面的归纳和总结。针对SCR脱硝技术的核心部件催化剂,分别根据活性组分以及活性适用温度区间进行了分类总结。目前应用比较广泛的为高、中温SCR脱硝催化剂,低温催化剂依然处于研究阶段,主要集中在通过对活性组分或者催化剂载体的改性研究。寻找合适的低温催化剂依然是脱销技术研究的重中之重。
Two main techniques of low temperature denitrification, SCR denitrification and plasma denitrification were summarized in this paper. For the core component catalyst of SCR denitrification technology, the classification was summarized according to the active component and the applicable temperature range. Now high and medium temperature SCR denitration catalyst was widely used, but catalyst at low temperature is still in the stage of research, mainly concentrated in through the modification research of active component or catalyst carrier. Finding a suitable low temperature catalyst is still the most important task in the research of unmarketable technology.
