Recovery of thiophen in simulative crude benzol by extraction with ionic liquid
摘要
Abstract
To recover thiophen in crude benzol, the ionic liquid was synthesized by the reaction of equimolar N-methy]imidazole with trimethyl phosphate. The ionic liquid was used as extraction desulfurization agent to remove thiophen in simulative crude benzol, and the used ionic liquid was regenerated to recover thiophen. The effects of extraction time, extraction temperature, the volume ratio of ionic liquid to simulative crude benzol, the repetitive performance of the ionic liquid on the rate of thiophen removal from the simulative crude benzol were investigated, and the recovery of thiophen during the ionic liquid regeneration was discussed. The results show that optimal desulfurization conditions are 30 min, 40℃ and V( ionic liquid) : V( simulative crude benzene) =1:1, the sulfur removal is 30. 48% ; the ionic liquid could be used repeatedly for 3 times. The used ionic liquids could be regenerated and about 66. 20% of the thiophen is recovered during regeneration by vacuum distillation. After regeneration, the extraction desulfurization performance of the ionic liquid remains almost unchanged.关键词
