  • 摘要: 本文以对氯甲基聚苯乙烯微球为前驱体制备了多孔碳材料CCMPS，并利用MgCl2对其进行表面修饰制得了在较低CO2浓度环境中具有高效CO2吸附性能的吸附剂MgCl2（n）/CCMPS.探究了吸附时间，MgCl2含量和气体流速对CO2吸附性能的影响，并对CO2吸附动力学进行了研究.研究表明，MgCl2（n）/CCMPS的CO2吸附动力学符合Bangham模型.吸附时间为10 min，气体流速为10 mL·min-1时，CO2吸附量可达158.4 mg·g-1.循环10次，吸附量保持稳定.
    Abstract: Porous carbon of CCMPS was prepared using p-chloromethyl polystyrene microsphere as precursor. Then, the modifiers of MgCl2(n)/CCMPS with efficient CO2 adsorption performance in a low CO2 concentration were synthesized by the introduction of MgCl2 on the surface of CCMPS. In the present study, the influence of adsorption time, the content of MgCl2 and gas flow rate for CO2 adsorption performance were investigated. Besides, the dynamic properties of CO2 adsorption was also studied. The results show that the dynamic properties of MgCl2(n)/CCMPS are in compliance with the Bangham model. In this study, the maximum capacity of 158.4 mg·g-1 is achieved after the adsorption for 10 min in a flow rate of 10 mL·min-1. In addition, the capacity keeps stable after 10 cycles of adsorption-desorption process.
