To reveal the chemical species of copper,typically the low-valence speices,in Cu-Zn-Al catalyst prepared by complete liquid-phase method before reduction,the effects of heat-treatment atmosphere,interactions among all components and copper precursor on heat-treatment have been systematically studied during the heat treatment of several different kind of copper precursor in liquid paraffin.The results showed that Cu²⁺ could be reduced by liquid paraffin under heating condition.The Cu⁺ is formed before the formation of Cu.The reductive degree of Cu²⁺ was related with the category of copper salts and heat-treatment temperature.CuO can be reduced to Cu₂O by liquid paraffin at 240℃,and then to Cu at 300℃.The copper nitrate could be easily reduced by liquid paraffin than copper acetate at the same temperature.The reason of the low-valent copper appearing in Cu-base catalyst prepared by complete liquid-phase method before reduction could be attributed to the presence of liquid paraffin.
