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.

通过比较微波改性活性炭前后的吸附脱硫能力，结合它们的表面物理和化学性质的变化分析，确认微波改性活性炭的脱硫性能有显著提高，其作用机理在于微波处理后，活性炭表面微观形貌发生了较大的变化，化学基团发生分解，碱性特征增强，表面含氧量减少，以CO形式释出的含氧官能团分解后产生的活性部位和吡咯氮官能团数量增加，吸附SO〓的表观活化能降低。
