Abstract

The basic strength of the MgO catalyst was enhanced by impregnating it with KF to synthesize a highly active catalyst for the bio-diesel production. To increase basicity, KF impregnated on synthesized MgO in laboratory. The synthesized catalyst was characterized using $N_2$ adsorption-desorption, X-Ray diffraction, X-Ray fluorescence, and $CO_2$ temperature programmed desorption analyses. Bio-diesel was produced from soybean and methanol and its fatty acid methyl ester content was measured to evaluate the activity of the catalyst. The catalyst impregnated with 30 wt% KF exhibited the highest activity, which was attributed to its abundant intermediate base site.

본 연구에서는 기존 MgO의 염기세기를 증가시켜 전이에스테르화 반응에 있어 보다 좋은 활성을 가지는 촉매를 만들고자 하였다. MgO를 실험실에서 제조한 후 지지체로 사용하였으며 염기세기를 증가시키기 위하여 KF를 함침법으로 담지하였다. BET, XRD, XRF, $CO_2$ TPO로 촉매의 특성분석을 하였고, 대두유과 메탄올을 사용하여 바이오디젤을 합성한 후 지방산메틸에스테르 함유량을 측정함으로써 촉매의 활성을 알아보았다. 결과적으로, KF를 30% 담지한 촉매가 활성이 가장 좋은 것으로 나타났다. 이는 전이에스테르화 반응에서 중간세기 염기도가 더 많이 관여하기 때문으로 보인다.
