Abstract��
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.
