摘要

本研究以實驗方式在固定床上量測活性碳在鹽酸溶液中含浸氯化亞銅 (CuCl)對於一氧化碳及二氧化碳吸附/脫附之影響。吸附劑特性以液態氮吸附、電子顯微照相及X-ray加以分析，由實驗結果發現含浸氯化亞銅之活性碳可增加一氧化碳及二氧化碳吸附。並以實驗方法探討一氧化碳濃度、二氧化碳濃度、吸附溫度、含浸的鹽酸濃度對於一氧化碳及二氧化碳吸附的影響。得知一氧化碳及二氧化碳吸附量會隨著濃度及含浸的鹽酸濃度增加而增加。
由研究中得知氯化亞銅含浸於活性碳表面的量和含浸時所使用之鹽酸濃度有關。
在CO/CO2 雙成分系統之吸附程序中，一氧化碳出口濃度會超過入口濃度，在脫附程序中二氧化碳脫附曲線會有高原區域。這是因為在含浸氯化亞銅之活性碳中，二氧化碳吸附力比一氧化碳吸附力強。

The single-component adsorption and desorption characteristics of CO and CO2 on the activated carbon impregnated with Copper (I) Chloride in different concentration of HCl solution were measured by fix-bed runs. The characteristics of CuCl impregnated activated carbons were examined by N2 adsorption, SEM, and X-ray. It was found that the impregnation of CuCl effectively increased CO and CO2 adsorption. The effects of CO and CO2 concentration, adsorption temperature, and impregnated HCl concentration were investigated. The CO and CO2 adsorbing capacity of impregnated CuCl activated carbon increases with the increase of CO concentration, CO2 concentration, and impregnated HCl concentration.
The amounts of CuCl impregnated on the surface of activated carbon were affected by the impregnated HCl concentration, i.e., the solubility of CuCl in HCl solution.
In the CO/CO2 binary component system, the effluent concentration of CO generally overshoots its inlet concentration during the adsorption steps, and CO2 desorption curves in the desorption steps generally exhibited a plateau region. It may be due to the higher adsorption of CO2 on the impregnated CuCl activated carbon than that of CO.
