摘　　要：阐述了硫醇氧化催化剂JX-2A和JX-2A^+的性能。试验证明:JX-2A和JX-2A^+具有硫醇氧化活性高、稳定性好等特点,同时验证了硫醇氧化转化需要氧的参与,硫醇转化效果与氧含量密切相关。试验表明,TBHP(叔丁基过氧化氢)可以作为液化石油气脱硫脱臭工艺的氧源。JX-2A^+在以TBHP为氧源,液相及常温条件下,可有效地氧化硫醇,且无碱液排放。The catalytic performances of JX-2A and JX-2A^＋ for mercaptan oxidation are described. Experiments showed that the catalysts JX-2A and JX-2A^＋ had high mercaptan oxidation activity and good stability. Test results also proved that mereaptan oxidation needs oxygen and the result of mereaptan oxidation is correlated with the oxygen content. TBHP（Tert-butyl hydrogen peroxide） can be used as the source of oxygen in liquefied petroleum gas （LPG） desulfurization and sweetening process. JX-2A ^＋ can efficiently oxidate mercaptan in LPG into disulfides with TBHP at ambient temperature in liquid phase, without emission of alkali liquid.
