%X Addition of water steam into regeneration process was applied to enhance the performance of Cu-Bi catalyst in the reaction of acetylene hydrochlorination,and the stability of the catalyst was tested by multiple reaction-regeneration cycles.The results showed that compared with traditional regeneration method by air only which could lead 95% loss of reactive components in just 6 h regeneration cycles,the process involving water steam could transform bismuth chloride formed on the catalyst surface in the reaction process into bismuth phosphate which possesses excellent thermal stability.After 15 h regeneration cycles,only 20% Bi was lost,and the initial reactivity of the catalyst could still be recovered,which can make its industrial application possible.
