摘要
以切削法制备的商用多孔不锈钢纤维毡为催化剂载体,采用浸渍法制备CuO/ZnO/Al2O3结构整体催化剂,研究其对甲醇水蒸气重整制氢性能的影响.采用扫描电镜(SEM)对多孔不锈钢纤维毡结构整体催化剂进行微观形貌分析.通过改变反应空速和反应温度,考察结构整体反应器与固定床反应器的制氢性能.结果表明:相比于固定床反应器,填充不锈钢纤维毡结构整体催化剂的反应器可强化反应过程的传质和传热,在反应温度为280℃时,氢气流量为 0.55 mol/h,甲醇转化率为95.07%;不锈钢纤维毡结构整体催化剂可降低甲醇水蒸气重整制氢的反应温度,减少反应系统的能量消耗.
Abstract
Using commercial porous stainless steel fiber felt(PSSFF)prepared by cutting method as catalyst carrier,the CuO/ZnO/Al2O3 monolithic catalyst was prepared by impregnation method,and its effect on hydrogen production from methanol steam reforming was studied.The microstructure of the monolithic structured catalyst of porous stainless steel fiber felt was characterized by scanning electron microscopy(SEM).By changing the reaction space velocity and reaction temperature,the hydrogen production performance of the microreactor and the fixed bed reactor was investigated.The results showed that compared with the fixed bed reactor,the structured catalyst and microreactor filled with PSSFF can enhance the mass transfer and heat transfer of the reaction.At the reaction temperature of 280℃,the hydrogen molar flow rate was 0.55 mol/h,and the methanol conversion rate was 95.07%.PSSFF structure monolithic catalyst can reduce the reaction temperature of methanol steam reforming and reduce the energy consumption of the reaction system.
