Cu-Zn-Al催化剂母体组成对其低变催化性能的影响

The Influence of Precursor Composition of Cu-Zn-Al Catalyst on It's Catalytic Properties for Low-temperature Shift Reaction

对Cu－Zn－Al低变催化剂中不同母体组成催化剂的催化性能进行了初步探讨，结果表明，Feitknechtite，Hydrozincite－like，Malachite－like母体对低变反应的活性和热稳定性各不相同，Feitknechtite母体具有优良的热稳定性，Feitknechtite和Hydrozincite－like结晶的搭配可以组成性能优良的低变催化剂．

The effect of various precursor compositions of Cu-Zn-Al Catalysts on the catalytic properties for low-temperatUre shift reaction was studied. For the different environment of Cu, Zn and Al component, Feitknecht compound, Hydrozincite-like and Malachite-line precursor would give the different catalytic activity, thermal-stability.Arranging in pairs of the phases of Feitknechtite and Hydrozincite-like is the base of excellent shift catalyst.
