초록

$MoO_3$, $SnO_2$ 및 $CeO_2$ 혼합촉매를 사용하여 대두유의 전이에스터화 반응에 의해 바이오디젤을 제조하였다. 제조된 촉매는 XRD 및 $NH_3$-TPD 등으로 특성을 분석하였다. 세 가지 금속 산화물 중 $MoO_3$가 가장 높은 활성을 보여주었으며, 반응에 사용된 촉매의 양이 7%일 때 바이오디젤로의 전환율이 가장 높았다. 또한, 반응물에 첨가된 물은 바이오디젤로의 전환율이 감소되었다. $MoO_3$와 $SnO_2$가 혼합된 촉매에서는 $SnO_2$와 $MoO_3$의 혼합비율이 5:5일 때 가장 높은 활성을 나타내었으며, $CeO_2$가 첨가된 촉매의 경우 첨가된 $CeO_2$의 첨가량이 20% 일 때 가장 높은 활성을 나타내었다. 또한 이들의 활성은 촉매들의 산점의 양과 상관관계를 보여주었다. 폐대두유를 이용한 반응에서는 약 30% 이상 바이오디젤로의 전환율이 감소하였다.

The production of biodiesel by transesterification of soybean oil was performed on $MoO_3$, $SnO_2$ and $CeO_2$ mixed oxides. The catalysts were characterized using XRD and $NH_3$-TPD. $MoO_3$ showed the highest activity among the three metal oxides. When 7 wt% of catalysts was introduced into the reactants, the highest activity was obtained and the water added to reactant decreased the catalytic activity. $MoO_3$ and $SnO_2$ mixed with 50:50 showed the highest activity and $CeO_2$ added with 20% on the $MoO_3-SnO_2$ mixed oxide also showed the highest activity. The catalytic activity showed to have a good relationship with the amount of acid site of catalysts. When the waste soybean oil was used as a reactant, the conversion was decreased about 30%.
