燃煤烟气汞排放控制

汞(Hg)是对环境和人类健康危害最严重的有毒重金属之一。汞从自然和人为来源中释放到大气,其排放控制已经引起了多方面的重视。本书介绍了自然和人为来源的汞污染和工业中的燃煤烟气的汞排放控制,特别是系统地描述了燃煤发电站的汞排放控制。本书对汞排放的控制理论和实验研究进行了论述,包括汞元素是如何被氧化成氧化汞以及烟气成分对汞形态转换过程的影响。本书全面地介绍了汞排放的控制方法，例如：电厂里现有的APCDs(空气污染控制设备)方法、吸附剂喷射法、煤燃烧的添加剂法和光催化法。本书作者系统性地给出了实验室规模、中试规模以及工业应用规模上的吸附剂喷射的实验研究成果，这有助于研究人员和工程师对吸附剂喷射法降低汞排放机理的理解以及应用这些方法在燃煤发电厂进行汞排放的控制。读者可以全面地了解可能的汞排放控制方法以及其中一些方法的工业应用。
