Abstract In this study, petroleum pitch-based activated carbon was prepared, and the correlation between the molecular weight of the pitch and the specific surface area of the prepared activated carbon was considered. The petroleum pitch was prepared by thermal synthesis of PFO (pyrolysis fuel oil) at 380∼430 ℃ to control the molecular weight of the pitch, and the product was analyzed by MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight). The activation proceeded by using KOH at 850 ℃ for 1 hour, and the pore structure of the prepared activated carbon was characterized by the Brunauer–Emmett–Teller (BET) method. The pitch synthesized at low temperature had a high specific surface area to 1855 m2/g due to the presence of volatile compounds with values of 128∼256 m/z, which formed cavities upon volatilization.

基于石油沥青分子量影响的双模型孔结构炭活化机理研究

摘要 本研究制备了石油沥青基活性炭，并考虑了沥青的分子量与所制备活性炭的比表面积之间的相关性。石油沥青通过PFO（热解燃料油）在380～430 ℃下热合成制备石油沥青，控制沥青的分子量，并通过MALDI-TOF（基质辅助激光解吸/电离-飞行时间）进行分析。 ）。用 KOH 在 850 ℃下活化 1 小时，制备的活性炭的孔结构通过 Brunauer-Emmett-Teller (BET) 方法表征。低温合成的沥青由于存在128～256 m/z的挥发性化合物，在挥发时形成空腔，比表面积高达1855 m2/g。
