Performance evaluation of low temperature carbonyl sulfur hydrolysis catalyst
At present,the reaction temperature of carbonyl sulfur hydrolysis catalysts devel-oped at home and abroad needs to be 100～400℃to give full play to their optimal catalytic activity,which has caused great inconvenience and energy waste to the actual industrial pro-duction and application.Therefore,the development of a high-efficiency and low tempera-ture carbonyl sulfur hydrolysis catalyst is the focus of research and industrial application.In this paper,the performance of low temperature carbonyl sulfur hydrolysis catalyst is evaluat-ed,and the industrial line test is carried out relying on the third combined unit of purifica-tion company.The test results show that under the conditions of temperature 60～70℃,pressure 5.3 MPa,feed gas flow 150 m3/h,and feed gas COS concentration 45 mg/m3,the carbonyl sulfur hydrolysis rate is≥99%,which provides a reference for the research direc-tion and industrial application of low temperature carbonyl sulfur hydrolysis catalyst.
