摘要

摘要本文综述了克劳斯法硫回收到H2S选择性氧化的研究进展。各国政府不断收紧法规，限制向空气中排放含硫化合物。这使得有必要不断提高从天然，炼油厂或煤气化geses中回收硫的水平，并且为此目的引入了克劳斯过程的许多改进。本文重点介绍了大多数硫回收装置中发生的反应机理、H2S与SO2或O2之间的反应以及COS和CS2水解或催化剂磺化等副反应。

Claus catalysis and H2S selective oxidation

Abstract This review article deals with the development of sulfur recovery from the Claus process to H2S selective oxidation. Governments are constantly tightening regulations to limit the emission of sulfur compounds into the air. This makes it necessary to constantly enhance the level of sulfur recovery from natural, refinery, or coal gasification geses, and many improvements in the Claus process have been introduced to this end. In this review, emphasis has been put on the mechanism of reactions occurring in most of the sulfur recovery units, reactions between H2S and SO2 or O2 and side reactions such as hydrolysis of COS and CS2 or sulfation of the catalyst.
