LS－901抗硫酸盐化作用催化剂的研制

ＬＳ－９０１催化剂是新研制的ＴｉＯ２基抗硫酸盐化作用硫磺回收催化剂，具有机械强度大、热稳定性和水热稳定性好、磨损率低等特点。该催化剂可直接采用工业原料生产，制备工艺简单，生产过程无“三废”污染。实验室的试验结果表明，ＬＳ－９０１催化剂的ＣＳ２水解反应活性和克劳斯反应活性、耐“漏Ｏ２”中毒性能等均优于进口ＴｉＯ２基催化剂。

STUDY ON LS-901 ANTI-SULFATING TiO_2 BASED CATALYST FOR SULPHUR RECOVERY

The recently developed LS-901 is an anti-sulfating TiO2 based catalyst for sulphur recovery, which possesses the characteristics of high mechanical strength, good thermal and hydrothermal stabilities,and low attrition loss. The catalyst may be produced by using industrial raw materials. The process of production was simple and no pollution as well. The comparative test results showed that LS-901 had better performances, such as CS2 hydrolysis activity, Claus sulfur recovery .and oxygen resistent activity, than the imported catalyst.
