用程序升温表面反应(CH3OH -TPSR)和程序升温还原反应 (H2 -TPR)考察了甲醇分解铜基催化剂的制备方法、组成及结构对其反应性能的影响。结果表明CH3OH -TPSR和H2 -TPR可作为甲醇分解催化剂筛选的有效手段。另外 ,CuO在载体Al2 O3 上状态、催化剂的表面积和孔结构对催化剂性能具有较大的影响
The effects of preparation method, composition and structure of methanol-decomposed copper-based catalyst on the reaction performance were investigated by using temperature-programmed surface reaction (CH3OH-TPSR) and temperature-programmed reduction reaction (H2 -TPR). The results showed that CH3OH-TPSR and H2-TPR could be used as an effective screening method for methanol decomposition catalyst. In addition, the state of CuO on the carrier Al 2 O 3, the surface area of the catalyst and the pore structure have a great influence on the catalyst performance
