摘　　要：以七台河煤与依兰煤进行配煤实验研究，在七台河煤与依兰煤配比1／1，碱炭比6／1，活化温度850℃，炭活化时间120min条件下对活性炭制备炭活化动力学进行研究。结果表明：以KOH为活化剂，配煤活化反应速率在800～950℃范围内，对烧失率B为一级反应，由阿仑尼乌斯公式可求出反应活化能为101．4032kJ·mol^-1，指前因子为3．1382×10^4。This paper studies on dynamics of carbonization and activation of preparation from activated carbon by blended coal from Qitaihe and Yilan, under the two type of coals as 1/1 ratio mixture, ratio of alkali/carbon of 6/ 1, activated temperature of 850℃, activated time of 120min. The results show the reaction rate of burn-off B is first-order reaction used KOH in 800 - 950℃. According to Arrhenius equation, it is calculated that the apparent activation energy of carbonization-activation reaction is 101. 4032 kJ · mol^-1, and the pre-exponential factor is 3.1382×10^4
