Abstract:

There is an urgent need but it is still a significant challenge to eliminate volatile organic compounds (VOCs) due to its serious threat to environment. This review summarized the treatment for low-concentration VOCs elimination with large air flow and focused on the adsorption and catalytic combustion treatment. Actually, there is a very large total amount of VOCs emission for low-concentration VOCs with large air flow. The VOCs concentration technology should be the effective way for reducing the cost during the VOCs treatment process, which could improve the VOCs concentration and decrease the air flow. And the development of high-performance VOCs adsorption materials is the key to VOCs concentration technology. This review introduced the properties of activated carbon, molecular sieve and other important adsorption materials in detail. Moreover, the principle of adsorption of VOCs and the effects of adsorption material properties and VOCs types on the adsorption result were also discussed. The application of activated carbon concentration-catalytic combustion technology and molecular sieve runner concentration-catalytic combustion technology in the treatment of low concentration VOCs with large air flow are prospected.

Key words: VOCs, active carbon, molecular sieves, adsorption concentration, catalytic combustion

摘要:

由于挥发性有机物(VOCs)会对环境造成严重的危害,因此VOCs的处理一直备受人们的关注,但发展高效的VOCs处理技术仍然存在严峻的挑战。本文针对大风量、低浓度VOCs的处理展开了综述,重点围绕吸附、催化燃烧处理展开讨论。对于大风量的低浓度VOCs,虽然浓度较低但VOCs排放量非常巨大。通过VOCs浓缩技术,提高浓度减少风量成为降低VOCs处理成本的有效途径。其中,发展高性能VOCs吸附材料是VOCs浓缩技术的关键。阐明了活性炭、分子筛等重要吸附材料的性质及其吸附VOCs的原理,并对吸附材料性质和VOCs种类对吸附效果的影响进行了探讨。展望了活性炭浓缩-催化燃烧技术和分子筛转轮浓缩-催化燃烧技术在大风量的低浓度VOCs处理中的应用前景。
