Siloxanes are widely used in industrial processes and consumer products. When landfill gas is used as fuel for gas engines, volatile siloxane in landfill gas causes serious damage to gas engines and pretreatment facilities. In this study, the applicability of various clay minerals was evaluated as the alternative adsorbents of activated carbon. SEM and BET analyses of illite, vermiculite, and activated carbon were performed for comparing those physical properties. Siloxane adsorption capacities of illite and vermiculite were estimated very high to 1.7 g/g illite, 3.8 g/g vermiculite respectively through the adsorption experiments of D5 siloxane.
