摘　　要：针对高含硫气田硫黄回收装置的运行需求,开发了新型抗氧化尾气加氢催化剂,并进行了工业应用,应用结果表明,该新型抗氧化低温尾气加氢催化剂具有较好的催化性能,在80%、100%和110%的运行负荷条件下,装置各项参数运行正常,3种工况下SO_(2)加氢转化率、CS_(2)水解转化率、脱氧率均能达到100%,烟气SO_(2)排放质量浓度均低于200 mg/m^(3),能够满足天然气田的环保要求及天然气净化厂大型硫黄回收装置的使用要求。According to the operation requirements of sulphur recovery unit in high sulphur gas field, a new type of oxidation resistant tail gas hydrogenation catalyst has been developed and applied in industry. The application results show that the new oxidation resistant low temperature tail gas hydrogenation catalyst has good catalytic performance. Under 80%, 100% and 110% operating load conditions, all parameters of the unit operate normally, and the SO_(2)hydrogenation conversion, CS_(2)hydrolysis conversion and deoxidation rate can reach 100% under three conditions. The emission mass concentration of SO_(2)in flue gas is lower than 200 mg/m^(3), which can meet the environmental protection requirements of natural gas fields and the use requirements of large sulphur recovery units in natural gas purification plants.
