硫改性硅酸盐吸附剂脱汞性能的实验研究
Removal of mercury vapor with sulfur-impregnated silicate sorbents
摘要
Abstract
Different modifiers on the S-containing natural silicate mineral material was modified to prepare different types of organic,inorganic S modified adsorbent.The performances of mercury removal efficiency for sorbents were investigated with a laboratory-scale fixed-bed reactor system in simulated flue gas.The sulfur-impregnated bentonite revealed 70% mercury removal efficiency at 70 ℃.Increasing of mercury removal efficiency was observed with rising temperature but the duration of mercury removal was shortened.60% mercury was removed from flue gas by cysteine-impregnated attapulgite between 120 ℃ to 150 ℃,temperature down to 70 ℃ will reduce the merucry removal rate.Sulfhydryl group and amino group existed in cysteine could trap mercury by chelation,but sulfhydryl group could not catch mercury alone.关键词
