Abstract
To prevent global warming due to the use of fossil fuels, many studies have been conducted on hydrogen production through methanol steam reforming. nevertheless, the effect of steam reforming by the promoters of the catalyst prepared by the use of the support and the impregnation method requires further study. therefore, through this study, basic physical properties such as catalyst surface properties and crystal state were observed according to the impregnation ratio of the promoters based on the Cu/γ-alumina support. in addition, by implementing methanol steam reforming, the effect of the composition of Zn and Zr used as promoters on the composition of steam reforming products was investigated. the basic physical properties of the catalyst could be observed through SEM-EDS, TPR, XRD. The hydrogen composition effect by zinc, which was expected to increase the hydrogen composition, was not clearly shown. however the effect on the carbon dioxide selectivity was well shown for both zirconium and zinc, and the Cu/Zn ratio of 1 showed better carbon dioxide selectivity by zirconium than the case of 2.5.
