“…When the inner core is permeable, the composite is called a core-shell composite as it is. In previous works [19][20][21] we presented exact analytical solutions for the step and the frequency responses of a constant molar flow semi-batch adsorption vessel containing particles with core-shell structure.…”

“…In addition, the FR technique allows for the determination of system characteristics (such as the amplitude and the phase angle of FR) over much smaller changes in the system conditions than are typically used for the step response technique. The aim of this work is to extend the step response analysis of the previous work [21] for the constant molar flow semi-batch adsorption vessel containing permeable core-shell composites to investigate FR characteristics of the system subject to a periodic modulation of inlet molar flow-rate. The model to be developed will include both the equilibrium interferences (at the fluid-particle interface and at the intraparticle core-shell interface) and the diffusion interferences (in the external film, in the outer shell-phase and in the inner core-phase).…”

Frequency response behavior of the constant molar flow semi-batch adsorption vessel containing coreshell composites is theoretically investigated. The periodic modulation of the inlet molar flow-rate into the vessel is considered as the forcing function to the response. Under the interaction between the core-phase and the shell-phase of the composite, both the response of the core-phase and the response of the shell-phase subject to the forcing function exhibit their own peaks on the out-of-phase characteristic curve and their own plateaus on the in-phase characteristic curve, respectively. The model to be developed will include the local linear equilibriums at the fluid-particle interface and at the intraparticle core-shell interface, the external diffusion, the intraparticle diffusion in the outer shell-phase, and the intraparticle diffusion in the inner core-phase.
