초록

실록산은 많은 소비 및 공업제품에 사용되고 있고 이들이 매립되어 발생되는 매립가스에는 휘발성 실록산을 포함한다. 휘발성 실록산을 포함한 매립가스를 가스엔진의 연료로 사용할 경우 매립가스내 휘발성 실록산은 가스엔진뿐만 아니라 전처리 시설에 큰 해를 입히게 된다. 따라서 본 연구에서는 매립가스내 휘발성 실록산 흡착제로서 활성탄 대용으로 천연 점토광물인 질석과 일라이트를 사용해 이의 유용성을 검토하였다. 질석, 일라이트 및 활성탄의 SEM 및 BET 분석을 통해 이들의 물성값을 비교하였다. 또한 일라이트 및 질석을 흡착제로 사용하여 D5 실록산의 흡착용량을 평가 하였는바, 각각 1.7 g/g 일라이트 및 3.8 g/g 질석의 대단히 높은 흡착용량을 나타내었다.

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.
