摘　　要：介绍了用于超级克劳斯工艺的LS-941 H2S选择性氧化催化剂的实验室研制及活性评价结果。该催化剂以惰性氧化铝为载体,以Fe/Cr为活性组分并添加专有助剂制备而成。在反应温度270℃、常压、空速为2500 h-1, (H2S)=1.0％, (O2)=0.6％及 (H2O)=20％的反应条件下,连续反应1000 h后,LS-941催化剂脱除H2S的平均转化率和选择性一直保持在90％以上,表明具有较高的活性和稳定性,已达到设计要求,可替代同类进口催化剂使用。The laboratory preparation and activity evaluation of Super-Claus catalyst LS-941 for selective oxidation of hydrogen sulfide were introduced. The said catalyst was composed of Fe/Cr active component with proprietary promoter and carried on inert alumina. After lOOOh continuous running at a reaction condition of 270℃, VHSV 2 500 h-1,0.1% H2S, 0. 6% O2 and 20% H2O, the average conversion of H2S kept more than 90%. The result indicated that the catalyst possessed high activity and good stability, which reached the design requirement and could replace the same type imported catalyst.
