| 摘 要： | 文章采用冷原子吸收法,选用经硫磺改性的活性炭和沸石对实验室中气态汞的吸附性能进行了实验研究。结果表明,改性后的活性炭和沸石对气态汞的脱汞率均有明显的提高,如对汞质量浓度560μg/m3的汞蒸气,负载8%硫的活性炭的脱汞率为90%,而未改性的活性炭的脱汞率为77%,负载8%硫的沸石相比于未改性的沸石的脱汞率由47%提升到67%。从经济角度分析,沸石脱汞比活性炭的经济效益更好。

| Abstract: | By using the method of cold atomic absorption,a bench-scale testing apparatus is constructed to evaluate the gaseous mercury adsorption performance of sulfur modified activated carbon and zeolite.The results demonstrate that by means of modification,the gaseous mercury removal rates of activated carbon and zeolite have been remarkably improved.In this experiment,compared with unmodified activated carbon and zeolite,the elemental mercury removal rates of activated carbon and zeolite with a sulfur amount of 8% each increased from 77% to 90% and from 47% to 67% respectively,with the vapor containing 560 μg/m3 mercury.Additionally,from an economic perspective,zeolite produces a better economic benefit compared with activated carbon. |
