摘　　要：本文研究了ＫＯＨ对氧化沥青的活化反应动力学参数，得出了ＫＯＨ与炭质材料作用的阿累尼乌斯方程，Ｋ＝８４５．Ｓ６ｅ￣（－４０·４９／ＲＴ），并对ＫＯＨ活化机理进行了初步分析和探索，提出了可能的反应方程式。Abstract In this paper,kinetic parameters of potassium hydroxide(KOH) activation were studied and reaction mechanism was preliminarily discussed and equations of activation reaction were put forward.The Arrhenius equation of KOH activation was LnK=6.74-4.87×103/T and the Ea was 40.49kJ/mol.The content of oxygen-containing in activation material had more effect on the activation results thanks to the production of organometelric compounds (R-OK and R-COOK, R Stands for aryl) adding active site of carbonaceous material The reaction equation between KOH and carbon was suggested:4 KOH+C-→K2CO3+K2O+2H2
