Progress and prospects of denitration technology
Miao Qiang
Abstract：In order to summarize the research achievements and elucidate the development trend of denitration techniques,as well as to establish a systematic denitration technology with proprietary intellectual property rights in China,this paper overviewed the current progress of domestic and foreign denitration techniques,and introduced several typical dry and wet processes of flue gas denitration technology.Accordingly,the most mature denitration process is the selective catalytic reduction denitration (SCR) process,while the selective non catalytic reduction (SNCR),plasma technology,oxidation and absorption processes also have a certain prospect and potential.As the mainstream denitration process,the improvement of SCR technique will mainly focus on the process optimization,high performance SCR catalyst development,catalyst life extension,and catalyst regeneration.The combination or integration of different denitriation processes based on different mechanisms is one of the important developing directions of denitration technology,and the process combining denitration and desulfurization processes should be researched.The innovation of denitration mechanism,integration of multi-stage or multi section,and development of novel recycling and regenerating denitration catalyst and adsorbents will become hot topics in this field.
