摘　　要：国家环保标准的日益严格和节能减排、清洁生产对硫磺回收尾气处理工艺和催化剂提出了更高需求,克劳斯尾气加氢催化剂逐渐由常规加氢催化剂转变为低温加氢催化剂。针对硫磺回收尾气加氢催化剂发展趋势,首次创新性提出加氢催化剂和水解催化剂组合使用理念,新型加氢催化剂载体制备技术取得重要突破。通过使用新型加氢催化剂载体,使SO_2的加氢转化率提高到99%以上。为进一步提高有机硫水解率,开发了低温有机硫水解催化剂。可使反应器出口尾气总硫体积含量降低至131×10^(-6)。通过实验室研究、现场试验和现场应用,使硫磺回收尾气低温加氢水解催化剂逐步成熟,并获得了良好的推广应用效果,环境效益显著。China sets higher requirements on sulfur recovery and tail treatment process and catalyst technology thanks to the country’s rigorous standards on environmental protection and clean production. The Claus tail-gas hydrogenation catalyst is gradually converted into low temperature hydrogenation catalyst from conventional hydrogenation catalyst. As for the development trend for sulfur recovery tail gas hydrogenation catalyst, the conception that hydrogenation catalyst is combined with hydrolysis catalyst is creatively proposed for the first time, making a breakthrough in preparation technology of new-type hydrogenation catalyst carrier. Based on use of new-type hydrogenation catalyst carrier, the SO2 hydrogenation conversion rate exceeds 90 percent. To improve organic sulfur conversion rate, low temperature organic sulfur hydrolysis catalyst is developed, making the total sulfur content in tail gas from the outlet of reactor drop to 131×10-6. The catalyst for sulfur recovery tail gas low temperature hydrogenation and hydrolysis is gradually matured on the basis of laboratory study, field test and field application. It has achieved good results for wide application and remarkable environmental performance.
