초록
바이오디젤 공정에서 비균일상 촉매는 생성물의 회수를 쉽게 하며 촉매를 재사용하는 장점이 있기 때문에 최근 연구가 활발히 진행되고 있다. 본 연구에서는 K2CO3/γ-Al2O3 촉매를 이용한 바이오디젤 생성 반응에서 촉매의 소성온도가 반응활성에 미치는 영향을 살펴보았다. 소성온도가 600 oC까지 높아짐에 따라 촉매의 활성이 높아졌으며, 그 이상의 온도에서는 촉매의 활성이 급격히 감소하여 소성온도가 촉매의 활성에 매우 중요한 영향을 주는 것을 확인하였다. 고온에서 이와 같은 활성감소는 Al-O-K와 Al-O2-K인 활성자리의 감소가 원인이었던 것으로 추정되었다.
The applications of heterogeneous catalyst have been relatively active area of research in the biodiesel process. These catalysts have the benefit of easy recovery and reusability of the catalyst. The objective of this study is to find out significant effect of calcination temperature on K2CO3/γ-Al2O3 catalytic activity in the biodiesel formation reaction. As a results, the temperature at which a catalyst was calcined had very important influence on the catalytic activity. The catalytic activity increased up to 600?, but it severely decreased above the temperature. The reduction of catalyst activity at high temperature would be due to the deduction of the active sites of Al-O-K and Al-O2-K.
