摘要
纳米流体作为一种新型传质增强技术,能有效地降低传质阻力,提高传质速率。综述了纳米流体强化CO_(2)吸收的研究现状。阐述了纳米流体的气液传质增强机制,重点讨论了纳米颗粒的种类、尺寸、表面官能化、浓度及初始CO_(2)浓度等因素对CO_(2)吸收的影响,简要介绍了几种纳米流体增强CO_(2)吸收的数学模型。最后对纳米流体在CO_(2)捕集领域的应用前景进行了展望。
As a new mass transfer enhancement technology,nanofluids can effectively reduce mass transfer resistance and increase mass transfer rate.The research actuality of nanofluids to enhance CO_(2) absorption was reviewed.The gas-liquid mass transfer enhancement mechanism of nanofluids was described.The effects of nanoparticle parameters(type,size,surface functionalization and concentration)and initial CO_(2) concentration on the enhancement of CO_(2) absorption were discussed and highlighted.And several mathematical models for enhancing CO_(2) absorption by nanofluids were briefly introduced.Finally,the application of nanofluids in the field of CO_(2) capture were prospected.
