活性炭用于烟气脱硫技术研究

随着我国经济的迅猛发展,以煤炭为主的能源消耗大幅攀升,大气中的污染物SO2含量越来越高。为了保护环境,我国政府对SO2排放总量的控制主要采取加大产业调整力度,加快淘汰落后产能,积极推进先进的SO2治理工艺。其中活性炭法脱硫技术被认为是极具开发前景的烟气脱硫技术,该技术的采用材料活性炭来源广泛,工艺过程无二次污染产生且可进一步回收硫资源,用过的活性炭也可再生并循环利用。该技术的研究应用符合我国国情的发展,具有一定的现实意义。阐述了活性炭用于烟气脱硫方面的机理及研究现状,并总结了存在的问题以及最新研究应用的实例。

Activated carbon for progress in flue gas desulfurization technology

With the rapid development of the domestic economy,coal as the main of energy consumption is in- creasing. Atmospheric sulfur content is more and more high. In order to protect environment and control SO~ e- missions timely and effectively ,the government propose measurements, in which including as follows= increasing the industry adjustment strength ,accelerating the elimination of backward production capacity ,actively promoting the advanced desulfurization process. The activated carbon desulfurization technology is considered to be the most promising flue gas desulfurization technology. Its desulfurization agent,activated carbon material source is wide. There are no second pollutions during the desulfurization process. The used activated carbon are renew- able and recycled, So the research and application of the technology conform to the development of Chinas national conditions. It has practical significance. The desulfurization mechanism and research status of activated carbon desulfurization are expounded. The existing problems and the latest research and application examples of the activated carbon used as desulfurization agent are summarized.
