活性炭吸附缓冲非稳态VOCs研究进展

活性炭类吸附剂可以有效地缓冲挥发性有机物(VOCs)的浓度负荷波动。综述了活性炭对非稳态VOCs吸附缓冲的作用原理及类型,从吸附剂、吸附质、进气性质和设备及操作条件等方面讨论了影响吸附缓冲性能的因素,并对今后该领域的研究方向提出了展望。指出:应当进一步研究吸附剂和吸附质的交互作用、波动负荷的影响以及VOCs在活性炭中的迁移扩散现象;同时,通过深层次的实验测试和模型模拟为反应器的设计和操作参数的估算提供指导。

Research progresses on adsorption buffering of unsteady VOCs emissions by activated carbon

Activated carbon adsorbent can effectively buffer the concentration loading fluctuation of volatile organic compounds （VOCs）. The principle and types of adsorption buffering of unsteady VOCs on activated carbon are summarized. The factors affecting adsorption buffering are discussed from adsorbents,adsorbates,gas inlet properties,equipments and operation conditions. The future research directions in this field are also prospected. It is pointed out that：The interaction between adsorbent and adsorbate,the effect of fluctuation loading and the migration and diffusion of VOCs in activated carbon should be further studied;At the same time,deep experimental tests and model simulations should be carried out for reactor design and operation parameter estimation.
