This paper summarizes the research status of the influence of different support properties on carbonyl sulfur hydrolysis catalysts and the influence of carrier pore structure on carbonyl sulfur hydrolysis conversion.The catalytic mechanism of carbonyl sulfur hydrolysis were discussed.The mechanism of oxy-gen poisoning,sulfur poisoning and chlorine poisoning of hydrolytic catalyst was emphatically introduced.On this basis,the future research direction of carbonyl sulfur hydrolysis catalyst was prospected,which provided theoretical support for the subsequent development of high efficiency hydrolysis catalyst.
