一种基于双核离子液体磷钨酸盐的催化油品氧化脱硫方法
摘要：
本发明涉及一种基于双核离子液体磷钨酸盐的催化油品氧化脱硫方法，其以正辛烷和二苯并噻吩为模拟油，以双核离子液体磷钨酸盐为催化剂，以极性溶剂为萃取剂，通过催化模拟油氧化脱硫。本发明具有如下优点：(1)催化剂活性高，用量少；(2)氧化脱硫反应条件温和，反应时间短；(3)双核离子液体磷钨酸盐性能稳定、可重复使用、分离工艺简单，后处理成本低、无污染、不腐蚀设备，环境友好，可望成为极具竞争力的清洁工艺路线。
摘要（英）：

The invention relates to an oil product oxidizing desulfurization catalyzing method based on dual-core ion liquid phosphotungstate.The method is characterized in that oxidizing desulfurization of simulated oil is catalyzed by taking normal octane and dibenzothiophene as the simulated oil, the dual-core ion liquid phosphotungstate as a catalyst and a polar solvent as an extraction agent.The oil product oxidizing desulfurization catalyzing method based on the dual-core ion liquid phosphotungstate has the advantages of high catalyst activity, little catalyst consumption, mild oxidizing desulfurization reaction conditions, short reaction time, stable performance, repeatability and simple separation technology of the dual-core ion liquid phosphotungstate, low aftertreatment cost, no pollution, no corrosion to equipment and environment friendliness, thereby hopefully becoming a competitive clean process route.
