摘要
煤中含有少量汞元素,在锅炉燃烧过程中会排放到大气给环境和人类健康带来危害。对汞的排放控制进行了实验研究,通过采用氯化锌溶液对GAC(活性炭)颗粒进行浸泡,研究它在低温下对气态汞的吸附特性。结果表明,GAC对汞的吸附取决于浸泡浓度、反应时间、实验温度、GAC特性等因素的影响。
Trace element Hg emitted from coalfired boiler would do great harm to environment and mankind health .The paper presents the experimental research on mercury adsorption by Granular Activated Carbons(GAC) impregnated with ZnCl2 at low temperature. Results indicate that the adsorption capacity is dependent on chloride content, contact time, adsorption temperature, and GAC' s properties.
