汽油和液化石油气中硫醇氧化反应机理的研究进展

Development of Research on Oxidation Reaction Mechanisms of Mercaptan in Gasoline and LPG

综述了国内外硫醇氧化反应机理的研究概况。介绍了碱性条件下硫醇的非催化氧化反应机理、硫醇的催化氧化反应机理、混合硫醇体系均相催化共氧化反应机理、固体碱存在下硫醇催化氧化反应机理、无苛性碱条件下硫醇催化氧化反应机理。认为进一步探讨硫醇的氧化反应机理是液化石油气和汽油脱硫醇研究的重要方向之一。

The research on the oxidation reaction mechanisms of mercaptan both in China and abroad is introduced. The non-catalytic oxidation reaction mechanism of mercaptan in caustic conditions, the catalytic oxidation reaction mechanism of mercaptan, homogeneous catalytic oxidation reaction mechanism of mixed mercaptan system, catalytic oxidation reaction mechanism of mercaptan in solid caustic conditions and catalytic oxidation reaction mechanism of mercaptan in non-caustic conditions are described. Further study of the catalytic oxidation reaction mechanism of mercaptan is very important for the gasoline and LPG sweetening operation.
