Volatile organic compounds (VOCs) are emitted from painting industry, mobile pollution sources life-type facilities, and so on Laundry facilities emit high concentrations of VOCs due to the use of petroleum solvent. An adsorption method is widely used as a method for removing VOCs in exhaust gas, and a carbonaceous adsorbent is mainly used as an adsorbent. However, carbonaceous adsorbents have a risk of fire and explosion when used for the control of VOCs. Therefore, development of non-carbonaceous adsorbents is required for the control of VOCs from laundry facilities. In this study, the adsorption and desorption properties of non-carbon adsorbents, such as silica (MCM-41, SBA-15, KIT-6), activated alumina, and aluminum silicate were investigated. These adsorbents were compared to commercial activated carbon. The laundry solvent was evaporated to make a concentration of 2000 ppm in the inlet gas. Adsorption and desorption experiment was conducted in the dry and wet gas conditions. The adsorption/desorption experiment was performed at a temperature of 30 °C. Desorption test was performed by injecting dry air. The exhaust gas was analyzed using gas chromatography (GC). Among the non-carbonaceous adsorbents, activated alumina showed the best desorption efficiency and relatively high adsorption capacity.
