TL;DR: In this article, the authors combine a simulated countercurrent flow system with a stationary magnetically stabilized fluidized bed to achieve continuous adsorption-desorption to separate components of a feedstream.
Abstract: The sorption process involves combining a simulated countercurrent flow system with a stationary magnetically stabilized fluidized bed to achieve continuous adsorption-desorption to separate components of a feedstream.

TL;DR: In this article, the authors describe a moving bed of a CATALYST, which deactivates in a zonal manner, being transferred down through a MULTIPASS RADIAL FLOW REACTOR, while a HYDROCARBON FEED STREAM FLOWS in a stepwise way.
Abstract: A MOVING BED OF A CATALYST WHICH DEACTIVATES IN A ZONAL MANNER IS TRANSFERRED DOWNWARD THROUGH A MULTIPASS RADIAL FLOW REACTOR WHILE A HYDROCARBON FEED STREAM FLOWS IN A STEPWISE COUNTERCURRENT FASHION ACROSS THE CATALYST. TO PROVIDE UNIFORM CONVERSION AND MAXIMUM USAGE OF THE CATALYST, A SONE OF ACTIVE CATALYST AND A ZONE OF DE- ACTIVATED CATALYST ARE BOTH MAINTAINED ACROSS THE HEIGHT OF A SINGLE SELECTED PASS BY CONTROLLING THE CATALYST TRANSFER RATE.

TL;DR: In this article, the effects of polydispersity and backmixing on diffusion-controlled mass transfer with irreversible chemical reaction in liquid emulsion membrane processes have been analyzed in terms of the advancing front model.
