PREPARATION OF ACTIVATED CARBONS FROM DAQING PETROLEUM COKE USING NaOH AS ACTIVATING AGENT

以大庆石油焦为原料 ,以NaOH为活化剂制备活性炭 ,考察了反应时间、反应温度和剂料比等因素对活化结果的影响 ,并对大庆石油焦的性质进行了分析 ,并与其他原料在相同的实验条件下的实验结果进行了对比。实验结果表明 ,当活化温度为 80 0℃ ,活化时间为 2h ,剂料比为 2∶1时 ,制得活性炭产品的质量最好。

The results of preparing activated carbons from Daqing petroleum coke with NaOH as an activating agent is reported. The reaction conditions including carbonization and activation conditions were optimized. All of the experiments were carried out in nitrogen gas. The effects of reaction parameters such as activation temperature and activation time on the porous structure and adsorption capacity of the activated carbons were investigated. The optimized reaction conditions were obtained, which are as follows:activation temperature, 800 ℃;activation time, 2 hours; the ratio of NaOH to petroleum coke, 2:1.
