LS系列硫磺回收催化剂工业装置使用总结

对比总结了LS系列催化剂的使用情况，结果表明，在一级转化器均装填LS-931Al2O3基催化剂的前提下，二级转化器上部装填LS－971脱氧保护型催化剂，下部装填LS－811Al2O3催化剂后，与单纯使用LS－931催化剂相比，单器转化率由64．1％提高到70．1％，有机硫水解率由96％提高到接近100％，两项合计使装置总硫转化率由95．1％提高到96．2％，若与两个转化器全部使用LS－811催化剂相比，则装置总硫转化率可由94．49％提高到96．2％使用效果更加显著。

Application of LS series of Sulfur Recovery Catalysts in Commercial Plant

The application of LS series of sulfur recovery catalysts was summarized in the paper. In the plant LS 93 Al 2O 3 basis catalyst was loaded in 1 st reactor, LS 971 deoxidized catalyst in the upper part of 2 nd reactor and LS 811 Al 2O 3 basis catalyst in the lower part of 2 nd reactor. In the comparing with LS 931 catalyst only, the conversion per each reactor was increased from 64 1% to 71%, the hydrolysis of organic sulfide from 96% to about 100%, and total conversion of sulfur from 95 7% to 96 2%. If it was compared with LS 811 catalyst only, total conversion of sulfur was increased from 94 4% to 96 2%, and its effect is more obvious.
