Abstract

In this study, the catalytic reaction characteristics for producing hydrogen using methanol steam reforming were investigated. Nickel and copper are frequently used in steam reforming reaction and methanol synthesis, were used as main active metals. As a support, hydrotalcite has a high specific surface area, excellent porosity and thermal stability, and has weak Lewis acid sites and basic properties. Hydrotalcite was used to identify catalysts of methanol steam reforming with catalytic activity and their properties. In this research, high reactivity was shown in the catalyst of copper metal with high reducibility. And increasing of active metal loading showed the higher the methanol conversion and hydrogen selectivity.

본 연구에서는 메탄올 수증기 개질 반응을 이용하여 수소를 제조할 수 있는 촉매 반응 특성을 조사하였다. 메탄의 수증기 개질 반응시 자주 사용되는 니켈, 그리고 메탄올 합성 시 자주 사용되는 구리를 주 활성금속으로 사용하였으며, 지지체로는 다공성 및 열적 안정성이 우수하고, 높은 비표면적, 약한 루이스 산점과 염기성을 가지고 있는 하이드로탈사이트를 이용함으로서 높은 활성을 가지는 촉매와 그 특성에 대해서 파악하였다. 본 연구에서는 환원성이 높은 구리금속의 촉매에서 높은 반응성을 나타내었으며, 각각의 촉매에서는 함침량이 높아질수록 메탄올 전환율 및 높은 수소 선택도를 보여 주었다.
