摘要:

氨气(NH3)作为一种危害性碱性有毒气体,不仅危害环境,而且会对人体造成不可逆伤害。在电子信息、能源等行业,极微量的NH3即可影响产品品质、降低过程性能。因此,NH3的深度脱除在工业上具有重要的意义。本文综述了近年来NH3深度脱除的工艺现状,分析了NH3脱除材料如离子液体、低共熔溶剂、改性活性炭、分子筛、改性氧化铝、金属盐类、金属有机框架材料、多孔有机聚合物、共价有机骨架材料、氧化石墨烯、普鲁士蓝类似物对NH3的分离性能。总结了深度脱除NH3的工艺特点和脱氨材料的性能,浅析了该领域发展面临的问题,并对未来的发展方向提出了建议。

Abstract:

Ammonia gas (NH3), as a harmful basic gas, not only pollutes the environment but also causes irreversible damages to human beings. In electronic information, energy, and other related industries, a trace amount of NH3 can affect product quality and reduce process performance. Therefore, deep removal of NH3 has important industrial significance. In this review, the status of deep removal of NH3 is reviewed, and the separation performance of various materials, including ionic liquids, deep eutectic solvents, modified activated carbon, molecular sieves, modified alumina, metal salts, metal-organic frameworks, porous organic polymers, covalent organic frameworks, graphite oxide, and Prussian blue analogs are discussed. The technological characteristics for deep removal of NH3 as well as the performance requirements for deamination materials are summarized. The challenges in this field are briefly analyzed with suggestions put forward for future development.

Key words: ammonia gas, deep removal, absorption, adsorption, separation
