摘　　要：阐述了硫醇氧化催化剂JX-2A和JX-2A+的催化性能。试验证明JX-2A和JX-2A+硫醇氧化催化剂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,无碱液排放。The catalytic performances of the mercaptan oxidation catalysts （JX-2A and JX-2A^＋） were studied. It was iound that both catalysts had high good activity and stability, and mercaptan oxidation needed the source of oxygen and the oxidative effect was correlated to oxygen content. TBHP （tert-butyl hydropemxide） could be used as the source of oxygen in liquefied petroleum gas （LPG） desulfurization and sweetening process. For catalyst JX-2A^＋, mercaptan in LPG could efficiently be oxidized into disulfides with TBHP at ambient temperature in liquid phase, without emission of alkali liquor.
