A methanol synthesis reaction is essential in CCUS (Carbon Capture, Utilization, and Storage) technology development research. Cu-Zn/Zn-Al oxide catalyst was designed for the methanol synthesis reaction to investigate the effect of calcination temperature on Zn-Al Oxides. Zn-Al oxide support was prepared by the co-precipitation method, and then the calcined various temperature. The Cu-Zn/Zn-Al oxide catalyst was prepared by co-precipitation in the direction of raising the loading amount of Cu and Zn on Zn-Al oxide support. The prepared catalyst was analyzed by N2 physical adsorption, XRD, H2-TPR, XRF, and NH3-TPD. The methanol synthesis reaction was performed under the condition of 250 oC, 40 bar, and GHSV = 4,000 h-1 with H2/CO/CO2/N2 gas in from the fixed bed reactor system. When the firing temperature of the support was lower than 700 oC, it was found that a high methanol yield was shown, and a stable reaction tendency with suppressed sintering was confirmed.
