摘要:

以六水合硝酸铈和尿素为原料,通过改变水热时间制备了CeO2?XX为水热时间,X=3、6、12、24 h)载体,对其进行等体积浸渍法负载活性组分Cu获得CuO/CeO2?X催化剂,将其应用于甲醇水蒸气重整制氢(MSR)反应中。通过XRD、BET、H2?TPR等表征手段,探索水热时间对CeO2?X载体、CuO/CeO2?X催化剂的结构和物化性质的影响,并考察了CuO/CeO2?X催化剂在MSR反应中的催化性能。结果表明,CuO/CeO2?6催化剂在MSR反应中展现出较好的催化活性;在反应温度为280 ℃、水醇物质的量比为1.2、甲醇气体体积空速(GHSV)为800 h-1的条件下,甲醇转化率可达92.8%。

Abstract:

CeO2?X (X is the hydrothermal synthesis time, X=3, 6, 12, 24 h) carriers were prepared by varying the hydrothermal synthesis time using Ce(NO3)3·6H2O and urea as raw materials, and CuO/CeO2?X catalysts were obtained by isovolumetric impregnation with active component Cu, which were applied to methanol steam reforming (MSR) reaction. The effects of hydrothermal synthesis time on the structure and physicochemical properties of the prepared CeO2?X carriers and CuO/CeO2?X catalysts were explored by XRD, BET, H2?TPR.The performances of the CuO/CeO2?X catalyst samples were evaluated in methanol steam reforming(MSR) reaction.The results show that the CuO/CeO2?6 has good catalytic activity. At the reaction temperature of 280 °C, when the molar ratio of water to methanol was 1.2, and the space velocity of methanol vapor (GHSV) was 800 h-1, the methanol conversion rate could reach 92.8%.
