| 中文摘要: |
| 氮氧化物(NOx)是大气污染的主要来源,目前较为成熟有效的脱硝技术就是氨选择性催化还原(NH3-SCR)技术。对NH3-SCR脱硝催化剂抗中毒性能的研究已经成为脱硝领域的重要研究课题之一。本文综述了水、硫、碱金属、重金属对NH3-SCR脱硝催化剂的毒化作用和提高NH3-SCR脱硝催化剂抗中毒性能策略方面的研究进展。并对将来如何开发出具有低温高脱硝活性并在复杂工况下能够实现同时抗多种毒物的NH3-SCR脱硝催化剂进行了展望。 |
| 英文摘要: |
| Nitrogen oxide (NOx) is the main source of air pollution. At present, the relatively mature and effective denitration technology is ammonia selective catalytic reduction (NH3-SCR) technology. The research on the anti-poisoning performance of NH3-SCR denitration catalysts has become an important topic in the field of denitration. In this paper, the toxic mechanisms of water, sulfur, alkali metals and heavy metals on NH3-SCR denitration catalysts and the strategies for improving the anti-poisoning performance of catalysts were reviewed. In the future, it is of vital significance to develop NH3-SCR denitrification catalysts with low temperature and high denitrification activity and to realize simultaneous resistance to multiple poisons under complex conditions. |
