同时脱硫脱硝固态反应剂研究进展

针对于干法同时控制热力发电厂NO_x和SO_2的排放,综述了近年来研究较广泛的钙基吸收剂、改性活性炭吸收剂、γ-Al_2O_3吸收-催化剂、天然锰矿石反应剂等几种同时脱硫脱硝固态反应剂的结构特性,以及脱硫脱硝效率。根据这几种固态反应剂的研究现状指出了应更进一步对氮氧化物和硫氧化物在同时脱除时的相互影响进行研究,从而提高同时脱硫脱硝效率。

Overview of Solid Sorbent for Simultaneous Desulfurization and Denitrification

Aimed at simultaneously controlling NOx and SO2 emission from coal -fired power plants by dry method ,the paper reviewed the structural features and the efficient of desulfuration and denitration of several solid reagents which has got exten-sive research in these years ,such as calcium - based sorbent ,modified activated carbon sorbent ,γ - Al2O3 sorbent - catalyst and nature manganese ore .According to the research state of these solid reagents it pointed out that the interaction between NOx and SO2 should be further researched in order to improve the simultaneously removal efficiency of NOx and SO2 .
