离子液体在氨气分离回收中的应用及展望
Applications and perspectives of NH3 separation and recovery with ionic liquids
摘要
Abstract
As one of the typical alkaline and poisonous pollutants, ammonia (NH3) is widely considered as a primary factor for the formation of fog and haze, which has caused a wide range of environmental problems and serious harm to human health. The traditional technologies for NH3 separation, like water scrubbing and acid scrubbing, have been applied in industries. However, some inherent drawbacks, such as severe corrosion, heavy pollution, high energy consumption, and hard to recover NH3 resources come with yet. Ionic liquids (ILs) provide a novel way for efficient and energy-saving separation of NH3 owing to their extremely low vapour pressure, good chemical/thermal stability and tuneable acidity and alkalinity. In this review, the recent advances on conventional ILs, functionalized ILs and IL-based solvents and materials for NH3 absorption/adsorption have been overviewed. The NH3 absorption capacities in different ILs were summarized and the effect of cations, anions and functional groups on NH3 absorption and the mechanisms have been discussed, and the research and development trend of this direction are discussed.关键词
