Abstract

Volatile Organic Compounds (VOCs) are a class of pollutants that have recently received much attention in atmospheric and indoor air pollution problems. They are precursors for PM 2.5 and ozone generation. The removal of VOCs emitted from exhaust gases is an urgent problem to solve air pollution. Adsorption is one of the most promising VOC abatement technologies, with the advantages of high purification efficiency, low cost, and simple equipment. The adsorbent plays a critical role in VOCs removal efficiency. Zeolite is a rapidly developing material due to its highly ordered and flexible microporous structure, good stability, and abundant surface modification. In this paper, the influence of zeolite properties, including framework structure, pore properties, and surface cations, on VOCs adsorption performance is analyzed. The VOCs adsorption performance on different zeolite adsorbents in the presence of water vapor is compared. The influential factors on the mass transfer kinetic properties of VOCs adsorption are summarized. Finally, an overview of zeolite honeycomb adsorbent applications for industrial use is presented, including multi-tower fixed bed adsorption and zeolite rotor adsorption.

沸石吸附去除挥发性有机物的研究进展

挥发性有机化合物(VOCs)是近年来在大气和室内空气污染问题中受到广泛关注的一类污染物。它们是PM 2.5和臭氧产生的前体。废气中挥发性有机化合物的去除是解决大气污染的迫切问题。吸附法具有净化效率高、成本低、设备简单等优点，是最有前途的VOC减排技术之一。吸附剂对VOCs的去除效果起着至关重要的作用。沸石具有高度有序柔性的微孔结构、良好的稳定性和丰富的表面改性，是一种发展迅速的材料。本文分析了分子筛的骨架结构、孔隙性质和表面阳离子对VOCs吸附性能的影响。比较了不同沸石吸附剂在水蒸气存在下对VOCs的吸附性能。综述了影响VOCs吸附传质动力学性能的因素。最后综述了沸石蜂窝吸附剂在工业上的应用，包括多塔固定床吸附和沸石转子吸附。
