Fe基离子液体中Schiff碱Co络合物催化氧化燃油脱硫
Oxidative desulfurization of fuels catalyzed by Schiff-base cobalt complex in Fe-based ionic liquid
摘要
Abstract
The oxidative desulfurization performance on model oil with thiophene was investigated with ionic liquid FeCl3/BmimCl and Schiff-base cobalt complex CoL and oxygen as the desulfurization system. Thiophene removal rate could reach 96%under the optimum condition,in which model oil dosage was 25mL,mole ratio of FeCl3/BmimCl was 1∶1 and its dosage was 8 mL,oxygen flow rate was 50 mL/min,reaction temperature was 62℃,CoL dosage was 0.13g,reaction time was 6h. The final thiophene content in the desulfurized model oil could be less than 50μg/g,and the oxidation product of thiophene was SO42−. The ionic liquid FeCl3/BmimCl could be recycled 4 times without significant decrease in desulfurization capability. The oxidative desulfurization rate of diesel oil could reach 100%with the above desulfurization system,which had good application prospect.关键词
