This article reviews the regulatory effects of COS hydrolysis catalyst carriers and active compo-nents on their catalytic performance,hydrolysis mechanisms,and the research status of factors affecting catalyst catalytic activity in industrial atmospheres.It was found that the COS hydrolysis catalyst prepared by loading alkali metal active components on alumina based composite carriers can better improve the ac-tivity and stability of the catalyst.The COS hydrolysis reaction has obvious alkaline catalytic characteris-tics,and the concentration of CO2 and O2 in industrial atmosphere has a significant impact on the oxygen and acid resistance of the hydrolysis catalyst.The generation of elemental sulfur and/or the sulfation of the catalyst surface are the main reasons for catalyst deactivation.The development trend in the future is to prepare a new type of COS hydrolysis catalyst with high activity and high oxygen and acid resistance by analyzing the deactivation factors of the catalyst,and to extend the lifespan of the catalyst by combining it with the optimization of hydrolysis catalytic reaction process parameters based on industrial gas source and hydrolysis thermodynamic kinetic conditions.
