In this work, the catalytic removal of HCl over Cu/Ni complex-loaded activated carbon fibers (ACFs), which were prepared by a direct metal plating method, was studied as a function of Ni content when Cu content on ACFs was fixed. The surface properties of the ACFs were determined by AAS, XRD, and SEM measurements. N2/77K adsorption isotherms were investigated by BET and D-R plots to characterize the specific surface areas and pore volumes, respectively. Hydrogen chloride removal efficiency was confirmed by gas detecting tube. As experimental results, the nickel content on the ACF surfaces was increased with plating time. However, a gradual decreases of adsorption properties in increasing the plating times was observed while metal content on ACFs was increased. The hydrogen chloride removal efficiency of metal complex-loaded ACFs showed higher efficiency of HCl removal than that of untreated ACFs. These results indicated that both the adsorption properties and the metal content in ACFs played an important role in improving the HCl removal. |
