摘要: 甲基叔丁基醚(MTBE)作为我国车用汽油的重要调和组分,研究其深度脱硫技术具有重要意义。本文综述了MTBE前脱硫(炼厂C4、LPG原料脱硫)和后脱硫(MTBE产品脱硫)两类脱硫技术的研究应用进展,后脱硫方法重点介绍了精馏、萃取精馏、氧化和吸附四类脱硫方法,与前脱硫方法相比其具有工艺简单、成本低廉、可深度脱除不同途径引入MTBE产品中的不同种类和不同性质的硫化物等优点。分析了MTBE中硫化物来源和种类对脱硫效果的影响,指出了后脱硫方法是MTBE深度脱硫技术未来的发展趋势,提出了今后可以从MTBE中硫化物组成出发设计经济、有效的后脱硫方法的观点。

Abstract: Methyl tert-butyl ether(MTBE), as an important additive of vehicle gasoline, is significant for deep desulfurization. Two types of desulfurization technology application progress were reviewed, i.e., pro-synthetic and post-synthetic desulfurization. The post-synthetic desulfurization was discussed, with the emphasis on the extraction distillation desulfurization, oxidation desulfurization and adsorption desulfurization. Compared with pro-synthetic desulfurization, post-synthetic desulfurization has the advantages of simple technology, low cost and deep desulfurization of different sulfides. The effects of sulfides source and sulfide species in MTBE on desulfurization efficiency were analyzed. It was pointed out that post-synthetic desulfurization was of the most promising one. Based on the sulfide species in MTBE, effective and low-cost post-synthetic desulfurization can be conducted.

Key words: methyl tert-butyl ether, refinery C4, liquefied petroleum gas, pro-synthetic desulfurization, post-synthetic desulfurization
