摘要:

本文回顾了近年来室温离子液体(RTILs)在天然气净化方面的研究进展。RTILs是一类具有独特物化性质的新材料,被誉为是新一代的绿色溶剂,已广泛应用于有机合成、分析化学、分离科学和电化学等诸多研究领域。在发展"低碳经济"的大背景下,RTILs已经作为一种新的气体分离介质引入天然气工业。RTILs具有优良的气体溶解能力和可调的物化性能,为新颖的配方型天然气净化溶剂的开发提供了一个新的发展平台。特别是在天然气脱硫和二氧化碳捕集方面,RTILs与膜技术的结合展现出了诱人的工业应用前景。

Abstract:

This paper reviews the recent research progress of room temperature ionic liquid (RTILs) used in natural gas purification.RTILs are a class of novel materials with some unique properties.They are described as new type solvents and have been widely applied in organic synthesis,analytical chemistry,separation technology and electrochemistry.To develop low-carbon economy,RTILs as a new gas separation media,have been introduced in gas purification.Due to their sound gas solubility and adjustable properties,RTILs supply a new platform for the development of the formulation solution used in natural gas purification.Moreover,the combination of RTILs and membrane technology show a promising prospect in industrial application,especially in the field of natural gas desulphurization and CO2 capture.
