Abstract:
In the zeolite family, the silicoaluminophosphate (SAPO)-34 zeolite has a unique chemical structure, distinctive pore size, adsorption characteristics, as well as chemical and thermal stability, and recently, has attracted much research attention. Increasing global carbon dioxide (CO2) emissions pose a serious environmental threat to humans, animals, plants, and the entire environment. This mini-review summarizes the role of SAPO-34 zeolite membranes, including mixed matrix membranes (MMMs) and pure SAPO-34 membranes in CO2 separation. Specifically, this paper summarizes significant developments in SAPO-34 membranes for CO2 removal from air and natural gas. Consideration is given to a variety of successes in SAPO-34 membranes, and future ideas are described in detail to foresee how SAPO-34 could be employed to mitigate greenhouse gas emissions. We hope that this study will serve as a detailed guide to the use of SAPO-34 membranes in industrial CO2 separation.
摘要:
在沸石家族中,磷酸硅铝(SAPO)-34沸石具有独特的化学结构,独特的孔径,吸附特性,以及化学和热稳定性,最近,引起了很多研究的关注。全球二氧化碳(CO2)排放量的增加对人类构成了严重的环境威胁,动物,植物,和整个环境。这篇小型综述总结了SAPO-34沸石膜的作用,包括CO2分离中的混合基质膜(MMM)和纯SAPO-34膜。具体来说,本文总结了SAPO-34膜在去除空气和天然气中的CO2方面的重大进展。考虑了SAPO-34膜的各种成功,并详细描述了未来的想法,以预见SAPO-34如何用于减少温室气体排放。我们希望这项研究将作为SAPO-34膜在工业CO2分离中使用的详细指南。
