摘　　要：分别利用自来水、氨水、NaHCO3和NaOH等4种液相介质对内蒙活性焦进行再生实验研究，并通过活性焦分形特征研究，分析活性焦分形维数与脱硫效果的关系。研究结果表明，自来水与弱碱溶液的再生存在再生速率慢，脱附率不高等缺点，利用强碱如NaOH不仅可以加快脱附速率，而且脱附完全度高达97％以上；活性焦具有分形几何的特征，其分形维数与脱硫趋势存在一定的联系。Regeneration with Inner Mongolia activated cokes （ACs） after desulfurizing was conducted in tap water, ammonia,sodium bicarbonate and sodium hydroxide solution respectively. Using ACs characteristics of fraetal geometry to study the relationship of fractal dimension and desulfurization. The results show that regeneration rate and desorption efficiency of ACs in tap water or weak base solution are slower than those in strong base. Using sodium hydroxide solution not only speeds up the desorption rate, but also makes complete level of desorption up to 97%. ACs has the characteristics of fractal geometry, and its fractal dimension has connection with the desulfurization trend.
