The less the oxygen content and the more content of N element in the form of pyrrole-N were observed under stronger microwave power radiation. It was affirmed that the desulfurization capability of activated carbon could be greatly increased by microwave modification. According to the analysis on surface physical and chemical characteristics, a mechanism was concluded: Modified by microwave, functional groups begin to dissociate, alkalescency is enhanced, and surface oxygen content is reduced; the amount of active sites produced by dissociation of oxygen-containing groups increased, so did the pyrrole-N groups. Apparently, the activated energy of SO〓 adsorption decreased.

采用密度泛函数理论法计算结果表明，苯并噻吩的电负性χ为2.638，属软碱类物质；由于Ag^＋为软酸，活性炭负载Ag^＋离子，增加了其局部表面的软酸，从而增强了对苯并噻吩硫化物的吸附；由于Ni^2＋、Cu^2＋和Zn^2＋离子属交界酸，负载Ni^2＋、Cu^2＋、Zn^2＋离子增加了活性炭表面的交界酸，也在一定程度上提高了其表面对苯并噻吩硫化物的吸附；当活性炭表面负载了硬酸性Fe^3＋或Co^3＋离子，其局部表面硬酸增大从而降低了其对苯并噻吩的吸附。
