【摘要】 以草酸为原料，采用一步法合成了N-甲基吡咯烷酮草酸盐离子液体催化剂，将其应用于模拟油脱除碱性氮工艺。考察了离子液体催化剂反应时间、温度、剂油比、H₂O₂用量对喹啉脱除率的影响。实验结果表明：在反应温度为45℃,反应时间为40 min、剂油比为1∶10、无氧化剂条件下，喹啉脱除率可达98.59%,让离子液体重复使用4次后喹啉脱除率可达85.49%。更多还原

【Abstract】 N-methylpyrrolidone oxalate ionic liquid catalyst was synthesized by one-step method using oxalic acid as raw material, It is applied to simulate oil alkali removal sexual nitrogen process. The effects of reaction time, temperature, ratio of agent to oil and amount of H₂O₂ on the removal rate of quinoline were investigated. The results show that the removal rate of quinoline can reach 98.59% when the reaction temperature is 45 ℃, the reaction time is 40 min, the ratio of agent to oil is 1∶10, and the removal rate of quinoline can reach 85.49% after repeated use of ionic liquid for 4 times.更多还原
