摘要
采用热重法研究了酚醛树脂基球形活性炭（PHSAC）对苯蒸气的动态吸脱附性能。结果表明PHSAC对苯蒸气有良好的吸脱附性能，其动力学曲线可分为三部分随着比表面积的增大和吸附温度的降低，苯蒸气平衡吸附量增加。再生后，吸脱附性能没有明显变化。
The dynamic behavior of phenolic resin-derived spherical activated carbon (PHSAC) for benzene adsorption/desorption was investigated using thermogravimetry (TG). The results showed that PHSAC possessed good adsorption/desorption performance for benzene. The dynamic curve can be divided into three parts. The adsorption capacity increases as the increase of the surface area and the decrease of adsorption temperature. There is no significant decrease of benzene adsorption capacity for PHSAC after regeneration
