硫磺回收催化剂活性衰退原因分析及防止措施

Analysis on the Sulfur Recycle Catalyst Activeness Decline Reason and Its Preventive Measures

分析了硫磺回收催化剂活性衰退的原因及防止措施。对于因外部因素硫沉积、含碳物质沉积和硫酸盐化原因引起的催化剂活性衰退可分别采取除硫、烧炭和还原操作方法恢复其活性,延长催化剂的使用寿命。

Sulfur recycle catalyst activeness decline reason and its preventive measures are analyzed. Concerning sulfur deposition, the carbonaceous matter deposition and the sulfuric acid salinization due to exterior factors, the measures such as sulfur removal, coke burning and reduction operation can be taken to prolong the service life of the catalyst.
