摘　　要：对五种脱氯剂在固定床反应器中与HCl气体反应研究发现 ,在温度为 30 0℃ ,空速为 30 0 0h-1 ,进口HCl气体质量浓度为 1× 10 -3 mg m3 条件下 ,所有脱氯剂都能迅速与HCl气体发生反应 ,并且在反应开始的一段时间内 ,能使混合气体中的HCl气体质量浓度降低至小于 0 5× 10 -6 mg m3 ,其中EC0 2脱氯剂具有较好的化学反应性和较高的氯容量。同时发现在相同反应时间和相同空速条件下 ,随温度的升高 ,EC0 2脱氯剂的氯容量也随之升高 ,此外还研究了 5 5 0℃时EC0 2脱氯剂床层的氯分布。Five sorbents for chloride removal from high temperature gas were studied in a fixed bed reactor. The experimental results show that all the tested sorbents can rapidly react with HCl vapor at 300℃,and reduce the HCl vapor concentration from about 1×10 -3 mg/m 3 to 0 5×10 -6 mg/m 3. The EC02 sorbent self prepared presents the highest chloride capacity. The effects of reaction temperature on chemical reactivity of EC02 sorbent and distribution of chloride in the sorbent bed were studied. It is found that the higher the reaction temperature, the higher the chloride content of sorbent and sorbent in the upstream end of the bed is nearly saturated with the chloride whereas sorbent in the downstream end contained less than 2% of chloride.
