摘　　要：以粘胶基活性碳纤维(VACF)为原料,采用浸渍法制备了负载镍、钴、锰、镁等系列金属的粘胶基活性碳纤维(M/VACF),并通过测定试样在77K的氮气吸附等温线对M/VACF比表面积和孔结构进行了表征。考察了M/VACF的脱硫性能,分析了影响其脱硫性能的各种因素。结果表明,M/VACF的比表面积和孔结构不是影响M/VACF脱硫性能的主要因素,负载金属的种类是影响M/VACF脱硫性能的主要因素。Metal -loaded viscose rayon -based activated carbon fiber（M/VACF） was prepared by impregnation method for loading metals onto VACF, such as nickel, cobalt, manganese and magnesium. The specific surface area and pore structure of M/VACF were characterized by testing its N2 adsorption isothermal line at 77 K. The desulfurizing capability of M/VACF was investigated and the affecting factors were analyzed. The results show that the major factor affecting the desulfurizing capability of M/VACF is not its specific surface area and pore structure, but the kind of loaded metal.
