摘要
流化床膜反应器中所采用的膜主要有2类,一类为钯(及其合金)膜,另外一类为透氧膜。介绍了近十几年来流化床膜反应器的新型应用研究,主要集中在反应器概念设计、膜及其透过性能、以及流化床流体特性。提出未来有必要对流化床膜反应器中化学反应与膜分离过程的耦合这一关键科学问题进行深入的研究,揭示膜对流化床流体力学特性的影响和流化床对膜透过性能的影响机理,以及这两个过程的耦合机制。
Two types of membranes have been employed in fluidized bed membrane reactors, hydrogen pennselective membrane and oxygen perm-selective membranes. The studies focus on conceptual design of novel reactors, membrane fabrication and characterization, and reactor hydrodynamics. It is essential to study the coupling of chemical reaction and membrane separation in the future, to discover the influence of membrane on bed hydrodynamics, the influence of fluidization on membrane separation, and the coupling mechanisms of these two processes.
