| 摘 要： | 通过高温化学活化法和以高硫石油流化焦为原料、KOH为主要活化剂制备活性炭,研究了碱焦比、乙醇或丙酮和氮气流保护等对活性炭性能的影响。实验在直立管式炉内进行,选用单因素实验,结合比表面积和孔隙表征、元素分析、工业分析及苯酚吸附值测定,对样品进行评价。结果表明:活性炭比表面积和总孔容积随碱焦比增加而增加;乙醇或丙酮配入能提高样品比表面积和孔隙特性及其苯酚吸附能力;采用无氮气流保护反应系统,能增加样品BET表面积和总孔容积,并降低硫氮含量。

| Abstract: | A high sulfur oil sand fluid coke was used to produce activated carbon via chemical activated process with KOH and other reagents within a vertical tubular furnace. Activated carbons were analyzed for specific surface area, porous size distribution, elemental analysis, industrial analysis as well as adsorption of phenol. Experimental data indicated that increase in using KOH enhanced the specific surface area and porous volume, reagents of ethanol and acetone were advantageous to development of specific sur... |
