摘要:

二氧化碳是全球气候变暖的主要诱因,随着我国“碳达峰、碳中和”战略的提出,二氧化碳的捕集、储存、利用技术快速发展。纳米流体是以由纳米颗粒以预先指定的比例分散在无机或有机液相中产生的具有稳定均匀性的胶体分散系统,兼有纳米材料和液体的特性。纳米颗粒由于对传热和传质过程有着明显的强化作用,因此对二氧化碳的化学吸收具有较大的潜在工业应用价值。本文基于纳米流体的概念,从基液选择、稳定性以及传质增强机制机理阐述了纳米流体在二氧化碳吸收领域的应用;进一步综述了目前纳米流体用于二氧化碳吸收分离的研究进展,分析了基液组成、二氧化碳分压、物化特性等对二氧化碳吸收性能的影响及机理研究;最后展望了纳米流体在二氧化碳吸收分离领域的未来发展趋势。

Abstract:

Carbon dioxide is the main cause of global warming. With the proposal of my country’s “carbon peak and carbon neutral” strategy, the technology of carbon dioxide capture, storage and utilization has developed rapidly. Nanofluid is a stable and homogeneous colloidal dispersion system produced by dispersing nanoparticles in an inorganic or organic liquid phase in a pre-specified ratio, and has both the characteristics of nanomaterials and liquids. Nanoparticles have a great potential industrial application value for the chemical absorption of carbon dioxide due to their obvious strengthening effect on the heat transfer and mass transfer process. Based on the concept of nanofluids, this paper expounded the application of nanofluids in the field of carbon dioxide absorption from the perspective of base fluid selection, stability, and mass transfer enhancement mechanism; further reviewed the current research progress of nanofluids in carbon dioxide absorption and separation, and analyzed the effects of composition, partial pressure of carbon dioxide, and physical and chemical properties on carbon dioxide absorption performance and mechanism research. Finally, the future development trend of nanofluids in the field of carbon dioxide absorption and separation was prospected.

Key words: nanofluid, carbon dioxide, gas separation
