Control of automotive paint booth emissions using zeolite, polymeric, and carbon adsorbents

对包括臭氧和挥发性有机化合物在内的空气污染物日益严格的监管要求不断进行研究，以开发更有效的方法来减少向大气排放的挥发性有机化合物，并允许人类与环境更可持续地生存。吸附在空气处理中被广泛用于控制VOC排放，但不可逆吸附(又名鞋跟堆积)是一个共同的挑战。如果被吸附的物种积累在吸附剂上，则吸附剂的寿命会降低，系统的运行和维护成本会增加。因此，这项研究的目的是通过了解选定的吸附剂在捕获有机溶剂通常产生的VOCs方面的性能，并找到有效的方法来再生吸附剂以重复使用吸附剂，并回收VOCs以供再利用，从而将VOC的排放降至最低。这项研究将有益于许多工业部门，因为它将有助于降低有机蒸汽的排放，并改善加拿大的空气质量。此外，这项研究还将有助于在对加拿大具有战略重要性的领域培养高素质的人才。

Increasingly stringent regulations on air pollutants including ozone and VOCs warrant continuous research to develop more efficient approaches to reduce VOCs emissions to the atmosphere and allow for humans' more sustainable existence with the environment. Adsorption is widely used in air treatment for controlling VOC emissions but irreversible adsorption (aka heel buildup) is a common challenge. If adsorbed species accumulate on the adsorbent, the lifetime of the adsorbent decreases and operation and maintenance costs for the system increase. This research, therefore, will aim at minimizing VOC emissions through understanding the performance of select adsorbents in capturing VOCs commonly generated from organic solvents use, and finding efficient ways to regenerate the adsorbents to reuse the adsorbent and recover the VOCs for reuse. This research will be beneficial to many industrial sectors as it will contribute to lowering the emissions of organic vapors and enhancing the air quality in Canada. In addition, this research will contribute to the training of high quality personnel in area of strategic importance to Canada.
