摘要:

发展经济高效的烟气脱硝技术是大气污染控制领域的重要研究方向,利用微波诱导催化技术开展烟气脱硝已成为当前热点方向。本文对近年国内外研究人员关于微波诱导催化治理烟气NOx的研究成果进行了综述,详细介绍了微波还原脱硝和微波氧化脱硝相关成果,重点讨论了以碳酸氢铵和活性炭为还原剂的微波诱导还原催化脱硝技术以及ZSM-5、金属氧化物和钙钛矿型混合氧化物微波催化还原脱硝技术。最后通过对比微波还原脱硝和微波氧化脱硝两种方法,提出研发微波催化氧化脱硝技术、探究其反应机理是开发新型烟气脱硝技术的重要方向。

Abstract:

The development of economical and efficient flue gas denitrification technology is an important research direction of air pollution control, in which microwave-induced catalytic denitrification has become a hotspot. This paper summarizes the research results of domestic and foreign researchers on microwave-induced catalytic treatment of NOx in recent years, and introduces the related researches of microwave reduction denitrification and microwave oxidative denitrification, with the focuses on the usage of ammonium bicarbonate and activate carbon as reducing agent, and ZSM-5, metal oxide and perovskite-type mixed oxide as catalysts. Finally, it is proposed that the development of microwave catalytic oxidative denitrification and the exploration of its reaction mechanism are the important directions for the development of new flue gas denitrification technology.

Key words: catalyst, reduction, oxidation, microwave denitrification
