초록
상용촉매인 Johnson Matthey사 KATALCO 83-3 촉매를 이용하여 마이크로 채널 반응기 (micro-channel reactor: MCR) 형태에 따른 메탄올 수증기 개질반응을 통한 수소제조반응 특성 연구를 수행하였다. 반응온도 200~300 ℃, 공간속도 3,000~10,000 hr^(-1), 촉매 크기 0.05~2.2 mm 조건을 갖는 고정층 반응기에서 반응활성 실험을 수행한 결과, 촉매 크기 0.35 mm에서 최적의 반응활성을 나타났다. 이 결과를 토대로 stacked bed, boat bed 등 마이크로 채널 반응기 형태에 따른 반응활성을 연구한 결과， stacked bed type 마이크로 채널 반응기가 더 좋은 반응활성을 가짐을 알 수 있었다.
Commercial catalyst (Cu-Zn/AI2O3, Johnson Matthey Co., 83-3 Catalyst) was applied to the hydrogen production by steam reforming of methanol in the micro-channel reactor (MCR). The steam reforming of methanol was tested over Cu-Zn catalyst at temperatures in the range of 200 and 300 ℃, the catalyst size of 0.05~2.2 mm, the space velocity of 3,000~10,000 hr^(-1) in a fixed bed continuous flow reactor. The conversion of methanol and the yield Hz preferred high temperatures and low space velocities, and had optimal results with the particle size of 0.35 mm. Based on the results from experiments with fixed bed reactor, two types of MCR, boat bed and stacked bed MCRs, were studied. The stacked bed type MCR showed better methanol conversion compared with the boat type one.
