液固磁稳定床研究进展

Progress in Liquid-Solid Magnetically Stabilized Bed

鉴于液固磁稳定床在石油化工、生化工程及环境工程等领域具有广阔的应用前景,本文从流体力学特性、传质过程、返混与扩散等几个方面,对液固磁稳定床的研究进展进行了综述。

Magnetically stabilized bed(MSB),which has the advantages of both packed bed and fluidized bed,has the primary charateristics of low-pressure drops and higher mass transfer coefficients.Magnetically stabilized bed has been used in many fields,such as petrochemical field,biochemical engineering and environmental engineering.The progress on the hydrodynamic behavior,mass transfer,back-mixing and diffusion of the liquid-solid MSB has been reviewed.
