| Abstract: | Volatile organic compounds (VOCs) are the key precursors of PM2.5 and O3 in the atmosphere. Most of them are flammable and explosive, and some of them are toxic and hazardous substances, which are harmful to human health. Adsorption method is widely used for purification of VOCs due to advantages of its simplicity, high efficiency and low cost. This review summarized the types and characteristics of VOCs in industrial gas, the main factors affecting the efficiencies of adsorption and purification, such as adsorbent, physical and chemical parameters of adsorbents (specific surface area, porous structure, and surface functional groups), characteristics of adsorbate (molecular polarity, molecular structure, and boiling point), operating parameters (temperature, humidity, and concentration of VOCs) and the regeneration of adsorbent. Moreover, the problems existing in the purification of VOCs by adsorption were summarized and the future research directions were prospected. |
