自制高温脱氯剂性能研究

Study on a Self-made Chlorine-removal Agent for High Temperature Gas

以一种价廉易得的天然矿物及碱金属化合物为化学活性组分,制得一种新型高温脱氯剂GH1．该脱氯 剂在650℃、空速2500 h-1和进口氯化氢气体质量浓度为1．8 g／m3条件下的穿透氯容达到37.2％,同时机械强 度合格．考察了主要成分配比、空速和温度对脱氯性能的影响;并基于固定床反应器恒定模式行为,研究了高温 脱氯过程反应动力学．结果表明,氯化氢脱除过程主要受化学反应控制,同时产物层的扩散控制是不容忽视的．

A new chlorine-removal agent for high temperature gas was made of a cheap natural mineral and alkali compounds. The sorbent has high breakthough chlorine content of 37.2% (in the condition of 650 ℃、2 500 h-1 space velocity and 1.8 g/m3 HCl input concentration) and high mechanical strength. Effects of main component proportion, space velocity and temperature on sorbent properties were examined. Adsorption process was found to be influenced mainly by chemical reaction from the kinetics.
