Abstract

The coal is a useful industrial resource for a long time. However, coal waste is generated by the mining process. Coal wastes are the main cause of pollution in the surrounding environment, and the amount of coal waste is set at hundreds of millions of tons. Significant amounts of these components in the coal waste are $SiO_2$ and $Al_2O_3$, which is also the main source of zeolites useful in various industries. This study is that the synthesis-zeolite was prepared from coal waste and properties and adsorption performance of synthesis-zeolite were compared with commercial zeolite. The synthesis-zeolite is showed similar properties to the commercial zeolite and also showed excellent adsorption performance against atmospheric pollution induced gases ($CO_2$, Toluene, $SO_2$, etc).

석탄은 오랜 전부터 사용해온 유용한 산업 자원이다. 그러나 채굴과정에서 많은 폐기물인 석탄 폐석이 발생된다. 석탄 폐석은 주변 환경오염의 주범이며, 그 양 또한 수억 톤이 적치된 상태이다. 이러한 석탄 폐석에 포함된 성분 중 상당량이 $SiO_2$와 $Al_2O_3$ 성분이고 이것은 여러 산업에서 유용하게 사용되는 제올라이트의 주원료이기도 하다. 본 연구는 석탄 폐석을 이용하여 제올라이트를 합성하고, 상용 제올라이트와의 물성 및 흡착 성능을 비교한 것이다. 합성제올라이트는 상용 제올라이트와 유사한 물성을 보여주고 있으며, 대기 환경오염 유발가스($CO_2$, Toluene, $SO_2$, 등)에 대한 흡착성능 또한 우수하였다.
