Abstract CuO/CeO₂-ZrO₂/SiC monolithic catalyst was prepared by sol-gel method and applied to the hydrogen production reaction of methanol steam reforming. The effect of calcination temperature on CuO/CeO₂-ZrO₂/SiC monolithic catalyst was investigated by XRD, BET, H₂-TPR, N₂O titration and other characterization methods. The results showed that calcination temperature had a great influence on the catalytic activity of CuO/CeO₂-ZrO₂/SiC monolithic catalyst. Combined with the characterization analysis, the catalyst calcined at 500 ℃ had better Cu dispersion and larger Cu specific surface area. Under the conditions of 360 ℃ reaction temperature, 1.2 molar ratio of water to methanol and 4 840 h^-1 space velocity of methanol vapor gas, the conversion of methanol was 77.3%. This paper provides basic data for the development of monolithic catalysts.
