LS-981多功能硫磺回收催化剂的研制与工业应用

介绍了新型多功能硫磺回收催化剂LS-981的研发和工业应用结果。该催化剂具有较高的Claus反应活性、有机硫水解活性、理想的脱氧性能及良好的结构稳定性。在中国石化胜利石化总厂4 kt/a硫磺回收装置上的工业应用结果表明，LS-981催化剂对于过程气复杂，特别是含烃类较高的酸性气具有良好的适应性，可提高装置的总硫回收率，延长运转周期，装置总硫转化率达到96%以上，有机硫水解率达到90%以上。

PREPARATION AND COMMERCIAL APPLICATION OF LS-981 MULTIFUNCTION CATALYST FOR SULFUR RECOVERY

The development and commercial application of LS-981 catalyst, a new multifunction sulfur recovery catalyst, were introduced. LS-981 catalyst possessed high Claus reaction activity, high CS2 hydrolysis activity, good oxygen removal activity and excellent structure stability. LS-981 catalyst was applied in the 4 kt/a sulfur recovery unit of SINOPEC Shengli Petrochemical Complex successfully. The application results showed that LS-981 catalyst could process hydrocarbon containing sour gas, the total sulfur conversion over LS-981 catalyst was more than 96%, CS2 hydrolysis rate was over 90% and the operation cycle of the unit was prolonged.
