摘要: 首次提出以Brønsted酸性离子液体[BMIM]HSO4 和H2SO4 的复配体系作催化剂,用于汽油烷基化脱硫研究。研究结果表明,在相同反应条件下,相比硫酸,复配体系能够在最大限度不改变烯烃组成的情况下有效催化噻吩与烯烃进行烷基化反应;噻吩转化率随反应温度的增加而增加,但当温度超过45 ℃后,烯烃聚合速率增加幅度远大于噻吩转化幅度;噻吩转化率随反应时间的增加而增加,反应2h后反应基本达到平衡。

Abstract:

The application of BrØnsted acidic ionic liquids of [BMIM]HSO4 and H2SO4 as catalyst in alkylating desulfurization technology of gasoline was studied. The result shows that the mixture of [BMIM] HSO4 and H2SO4 has better selectivity than sulfuric acid on catalyzing the alkylation of thiophene and alkene, under the same reaction condition. The conversion rate of thiophene increases as reaction temperature increases, but when the temperature is higher than 45 ℃, hexene decreases sharply due to polymerization. The conversion rate of thiophene increases with the increasing of reaction time, it costs about 2h to meet the equilibrium of reaction between thiophene and hexane.
