文章导读

摘要采用溶胶凝胶法制备了CuO/CeO₂-ZrO₂/SiC整体催化剂,并将其应用到甲醇水蒸气重整制氢反应中。通过XRD、BET、H₂-TPR、N₂O滴定等表征手段,探究焙烧温度对CuO/CeO₂-ZrO₂/SiC整体催化剂的影响。结果表明,焙烧温度对CuO/CeO₂-ZrO₂/SiC整体催化剂催化活性影响较大。结合表征分析,其中500 ℃焙烧的整体催化剂具有较好的Cu分散度,较大的Cu比表面积。在反应温度为360 ℃,水醇物质的量之比为1.2,甲醇水蒸气气体空速为4 840 h^-1的条件下甲醇的转化率为77.3%。为整体催化剂的开发提供基础数据。

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.
