제목 Steam reforming and oxidative steam reforming of methanol over CuO-CeO2 catalysts
초록 Steam reforming (SRM) and oxidative steam reforming of methanol (OSRM) were carried out over a series of co-precipitated CuO-CeO2 catalysts with varying copper/ceria atomic ratio in the range of 3080 at.% Cu (=100*Cu/(Cu+Ce)). The effects of copper content, reaction temperature and O2 addition on catalytic activity were investigated. All the catalysts were characterized by using H2-TPR and N2 physisorption. It was found that BET surface areas of CuO-CeO2 catalysts decreased with increasing copper content and H2-TPR results showed that both peak area and the temperature of the peak maximum increased considerably with increasing copper content.The activity of CuO-CeO2 catalysts for the steam reforming and oxidative steam reforming of methanol increased with the copper content. Among the catalysts studied, 70 at% CuO-CeO2 catalyst showed the highest activity in the temperature range of 150-300 ℃ for both SRM and OSRM. It was observed that the reaction rate of SRM increased considerably with the addition of O2 into the feed stream.
