摘　　要：以煤质活性炭为载体，采用旋蒸浸渍法负载碱性金属氧化物，制备了活性炭基吸附剂，用于脱除气体中的硫化物，包括硫化氢、丙硫醇和噻吩。采用x射线衍射分析、孔容及比表面积分析对制备的吸附剂进行了表征，对吸附剂脱除硫化氢、丙硫醇、噻吩等3种硫化物的脱硫性能和反应热效应进行了评价，并考察了空速对反应热效应的影响。试验结果表明：制备的活性炭基吸附剂可以有效脱除硫化氢、丙硫醇、噻吩等3种硫化物，穿透硫容达到50％以上；空速在考察的25—120h-1时，反应热效应随空速的增加呈线性增加的关系，实际工况下的使用空速不宜超过100h-1。The activated carbon based adsorbent is prepared by using coaly activated carbon as carrier and loading alkali metal oxide through rotary evaporation and impregnation method. The prepared adsorbent is adopted to remove sulfides in the gas such as hydrogen sulfide, propylene sulfide and thiophene. The adsorbent is characterized by XRD, pore volume and specific surface area analysis, and the sulfides removing performance and reaction heat effect of adsorbent are evaluated. The effects of volume space velocity on reaction heat effect are investigated. The results show that the adsorbent can remove sulfides effectively, and the breakthrough sulfur capacity can reach more than 50%. In addition, the reaction heat effect increases linearly with the increase of volume space velocity in the range of 25 - 120 h-1 , and the volume space velocity should not exceed 100 h-1 in actual operation conditions.
