아크로레인 산화용 Mo-V계 혼합산화물 촉매의 상승효과(I)
Synergistic Effects of Mo-V Based Mixed Oxide Catalysts for Acrolein Oxidation(Ⅰ)
초록
공침법으로 제조한 vanadium molybdate와 copper molybdat촉매의 기계적 혼합물과 V2O5와 MoO3의 기계적 혼합물을 아크로레인의 선택 산화반응용 촉매로 사용하여 각각의 금속산화물 사이의 상승효과에 대하여 고찰하였다. 반응실험 결과 혼합촉매를 사용한 경우 아크로레인의 전화율과 아크릴산의 수율이 증가하였으며 이는 remote control mechanism으로 설명 할 수 있었다 열중량 분석결과 혼합촉매에서 격자산소가 방출됨을 확인할 수 있었다.
Mechanical mixtures of vanadium molybdate and copper molybdate catalysts prepared by coprecipitation method, and those of MoO3 and V2O3 were used to study the synergistic effects between each metal oxide for the selective oxidation of acrolein. The catalytic activity results revealed that the conversion of acrolein and yield of acrylic acid were increased with the mixture catalysts and it could be explained by a remote control mechanism. Thermal gravimetric analysis confirmed the evolution of lattice oxygen in the mixture catalysts.
