Abstract A model for the sorption of gases onto bidispersed structured sorbent material in a batch system, subjected to small periodic perturbations of the system volume is developed. The model takes account of external film mass transfer resistance, coupled macropore and micropore resistance, and the surface barrier. The general model is linearised, and analytical solutions for the characteristic functions for slab, cylindrical and spherical macroparticle and microparticle geometries are determined, for both the general model and degenerate models which are applicable when one or more of the mass transfer resistances are negligible. The characteristic functions are examined to determine the effects of macroparticle and microparticle geometry and the rate controlling mechanisms on the frequency response spectrum. The limitations of the batch frequency response technique for investigation with sorbate-sorbent systems exhibiting H2- or L4-type isotherms are briefly considered.
