摘要：
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. © 2020, Chemical Industry Press Co., Ltd..
