| 摘 要： | 对兼具吸附和催化剂载体功能的多孔结构活性炭，以乙基纤维素为材料用相分离进行包覆。利用扫描电镜、热重分析仪、静吸附仪以及自动物理吸附仪对乙基纤维素包覆活性炭前后的表面形貌特征、比表面积和静吸附性能等进行了评价。结果表明，包覆后活性炭对低浓度苯蒸气静吸附性能基本无影响，比表面积和总孔容降低甚微。

| Abstract: | Activated carbon as the sorbent and catalyst support was capsulated with ethyl cellulose by phase separation methods. The activated carbon micro encapsulated was characterized by SEM, TG DSC and adsorption techniques. The results showed that the adsorption capability to low concentration benzene vapor on activated carbon had no influence after capsulation, and the specific surface area and total pore volume decreased a little. |
