제목 A study on the methanol steam reforming in micro-channels reactor
초록 Hydrogen production from methanol by steam reforming has been studied on a series of Cu/Zn based catalysts in a micro-channels reactor. Effects of catalysts preparation method, composition and undercoating buffer layer in micro channels wall for the adhesion between catalysts powder and the substrate structure have been studied. The catalyst containing 18.75 mole% ZrO2 in Cu/ZnO/ZrO2/Al2O3 catalyst was investigated activity with methanol conversion of 92% and outlet CO concentration of 0.108 mol% at 260oC reaction temperature. A micro-channels sheet had four holes for flow path and 34 parallel channels of a rectangular shape on it and the micro channels were 300 ㎛ wide, 200 ㎛ in deep and 20 mm long. Undercoating alumina as a buffer layer in micro channels wall have been improved coversion of methanol in micro-channels reactor compared to non-buffer layer in micro channels wall. It is shown that alumina as a buffer layer in micro channels wall has been improved adhesion between catalyst powder and channels wall so catalyst on the micro channels wall exhibited higher activity performance and stability as compared to non-buffer layer in micro channels wall.
