초록
메탄올 수증기 개질반응에 대한 적용가능성을 파악하기 위하여 메탄올 합성용 촉매인 ICI-M45와 수성가스 전환반 응용 촉매인 MDC-3와 MDC-7을 비교 연구하였다. 또한 수성가스전환 반응에 대한 세 촉매의 비교실험도 수행하였다. 그 결과 MDC-7이 메탄올 수증기 개질반응에서 가장 높은 전화율을 보였으며, H2와 CO2 생성속도 또한 높게 나타났다. 수성가스 전환반응용 촉매인 MDC-7과 메탄올 합성촉매인 ICI-M45를 이용하여 촉매 충진 방법에 따른 메탄올의 전화율에서의 변화를 살펴본 결과, MDC-7 단독보다 낮은 메탄올의 전화율을 보였다. 수성가스 전환반응에서도 MDC-7, MDC-3, 그리고 ICI-M45의 순으로 반응성이 감소하였다. 상기 두 반응에서 MDC-7이 가장 우수한 이유로는 높은 비표면적과 Cu의 분산도, 그리고 적절한 Cu와 Zn의 비율에 기인함을 확인할 수 있었다.
The comparison work was conducted for the methanol steam reforming among commercial Cu-based catalysts, viz. ICI-M45, which is for the methanol synthesis, MDC-3 and MDC-7, which are for the water-gas shift reaction. The catalytic activity for the water-gas shift reaction was also compared over three catalysts. Among them, MDC-7 showed the highest methanol conversion and formation rate of hydrogen and carbon dioxide at 473 K for the methanol steam reforming. To find out any promotional effect between ICI-M45 and MDC-7, three different packing methods with these two catalysts were examined. However, no synergistic effect was observed. The catalytic activity for watergas shift reaction decreased in the following order: MDC-7 > MDC-3 > ICI-M45. The highest activity of MDC-7 for the methanol steam reforming as well as the water-gas shift reaction can be due to its high surface area, copper dispersion, and an adequate Cu/Zn ratio.
