摘要

采用小型固定床反应器研究钙基吸收剂对单质汞的脱除效果。研究结果表明

汞入口浓度增加

单价汞的饱和吸附量增加;钙基吸收剂比表面积和孔容积越大

汞的脱除效果越好;反应温度对饱和吸附量有不利影响

但是在吸附的最初阶段有利于汞的脱除。

Abstract

A small-scale fixed bed reactor to study the effectiveness of elemental mercury (Hg°) removal by using Ca-based absorbent has been established. Results of study show that: the saturated adsorption capacity of Ca-based absorbent is increased with increasing the inlet mercury concentration

and more mercury is removed by Ca-based absorbent with large specific surface area and cavity volume; the reaction temperature is badly affecting the saturated adsorption capacity

but at first stage of adsorption it is beneficial to the mercury removal.
