Mercury-free catalysts for acetylene hydrochlorination have received wide attentions due to their considerable activity and environmental benefits. The research progress of mercury-free catalysts for acetylene hydrochlorination in recent years is reviewed. The main methods for improving the catalytic properties of non-noble metal catalysts and the effects of active component,support,and preparation process on catalytic activity are summarized. The relationship between catalytic activity and reaction mechanism of solid or liquid systems is presented. The conditions for the highly active, long life mercury-free catalysts of non-noble metal to be used in acetylene hydrochlorination are analyzed. Concerted catalysis of non-noble metals , various processing methods for supports , optimization of catalyst preparation,and application of ionic liquids will be the development trends of mercury-free catalysts for acetylene hydrochlorination.
