psr硫回收催化剂
sulfur recovery catalyst
1. 产品概述 product deion
在煤、石油和天然气的加工过程中产生大量的h2s气体，为了保护环境和回收元素硫，工业上普遍采用克劳斯过程，使用psr硫回收催化剂处理含有h2s的酸性气体。工业应用表明，在燃烧炉能达到的高温下，一般炉内h 2s转化率可以达到65%-75%，若采用二级克劳斯工艺，装置总硫转化率约为92-95%。
psr sulfur recovery catalyst is used to treat with the acid gases containing h2s for the sake of recovery sulfur element and environmental protection in oil refinery, chemical factory, iron & steel plant and natural gas treatment processes. the conversion of sulfur can reach to 65~75% in a ordinary bumer, 92~95% it react by two stages clause processes, furthermore to higher than 98% if by three clause reactors.
