摘　　要：根据国内外相关文献对活性炭材料如活性焦、活性半焦、活性炭及活性炭纤维脱硫脱硝动力学的研究情况进行了简要总结。脱硫脱硝动力学方程主要分为幂函数型和根据反应机理推导两种,由于研究者采用的原料或制备方法及条件不同,实验手段各异,实验结果如反应速率常数、活化能等值也不尽相同。而由反应机理所获得的动力学方程形式及参数也差异较大。因此,活性炭材料脱硫脱硝动力学仍有必要进行深入研究。The research on desulphurization and denitration kinetics of active carbon materials,such as activated coke,activated char（semi-coke）,activated carbon and activated carbon fiber,is summarized in this paper.From papers,the desulphurization and denitration kinetics can be divided into two types,one is power-law model and the other is obtained from reaction mechanism.Since the difference of raw materials,preparation conditions and equipments used,the results such as reaction constant and activation energy are different too.The different reaction mechanism also results in different kinetics equations and different parameters.Thus more research work is needed on active carbon materials desulphurization and denitration kinetics.
