| Summary: | 碩士 === 大同工學院 === 化學工程研究所 === 87 === The adsorption and desorption characteristics of CO on the activated carbon impregnated with Copper (I) Chloride in HCl solution were measured by fixed-bed runs. CuCl impregnated carbons were characterized by N2 adsorption, SEM, and X-ray. It was found that the impregnation of CuCl effectively increased CO adsorption. The effects of CO concentration, adsorption temperature, impregnant amount, impregnated HCl concentration, and particle sizes were also investigated on these carbons. The CO adsorbing capacity of impregnated activated carbon increased with the increase of CO concentration, impregnant amount, and impregnated HCl solution.
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.
Reversible adsorption/desorption characteristics were elucidated in the experiment. Adsorption isotherms of CO were measured and correlated by four isotherm equations. It was found that Dubinin-Radushkevich equation can fit the equilibrium data within 25% under the operating ranges.
