介绍了LS - 971脱漏氧保护型硫磺回收催化剂在中国石化济南分公司 5kt/a硫磺回收装置上工业应用的试验情况。结果表明 :该催化剂具有较好的活性和稳定性 ,置于第二级转化器上部使用后 ,可使装置尾气中的总硫含量小于 1% ,总硫转化率则稳定地保持在 96 %以上 ,完全可以满足克劳斯硫磺回收———SSR还原吸收法尾气处理装置的使用要求
The industrial application of LS - 971 deaerator oxygen - protected sulfur recovery catalyst to 5kt / a sulfur recovery unit of SINOPEC Jinan Branch was introduced. The results show that the catalyst has good activity and stability. When used in the upper stage of the second-stage reformer, the total sulfur content in the tail gas can be less than 1% and the total sulfur conversion rate can be kept stable above 96% , Fully meet the Krauss sulfur recovery --- SSR reduction absorption tail gas treatment device requirements
