“…Eqs. (19) and (20) mean that the sinusoidal part of FR dissipates and FR becomes the ultimate (i.e., long time) step response in the limit when ω * →0. However, it is not surprising that the ultimate step response is recovered from FR in the limit, since the forcing function given by Eq.…”

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.

The frequency response (FR) method, a pseudo-steady state relaxation technique employing perturbation frequency, plays an essential role in discriminating between multi-kinetic mechanisms in microporous materials for separation and catalytic processes. Experimental and theoretical principles are reviewed for three frequency response methods, including one commonly used batch system with volume perturbation and two recently developed flow-through systems with pressure or concentration oscillation. Even though these methods have different overall transfer functions, they can be linked closely through the adsorbed-phase functions, which account for individual or coupling of mass transfer resistances and heat effects. Mass transfer resistances include micropore diffusion, macropore diffusion, surface barriers, and external film resistance. By judicious application of FR methods, it is not only possible to identify dominating mass transfer resistances but also to extract reliable mass transfer coefficients based on corresponding mathematical models. Representative examples to display the ability of the FR methods in studies of zeolites, carbon molecular sieves, and other microporous materials are discussed. Mixture studies and future developments, including nonlinear frequency response and chemical reactions, have also been briefly described.
