The purpose of this study is to investigate selective adsorption of CO₂ from LFG (Landfill gas) by using commercialized NaX-type zeolite adsorbent under the ambient temperature and pressure. The experiment of CO₂ adsorption was carried out by using simulated LFG. The CO₂ adsorption capacity and separation efficiency of NaX-type adsorbent were investigated by analyzing gas flow rate and gas composition at inlet and outlet of the adsorption reactor. The adsorbed CO₂ were desorbed under decompression condition which 0.5 Torr or by air purge. Through the result to use simulated LFG, when the method of VSA was used, 73.2~75.3 mg of CO₂ was adsorbed per 1 g commercial adsorbent, when the method of air purge was used, 78.4~83.2 mg of CO₂ was adsorbed per 1 g of commercial adsorbent.
