- Аннотация: Five similarity criteria for adsorption systems have been formulated as follows: (1) the ratio of the adsorber length to the thickness of the front; (2) the adsorber output; (3) the relative molar density of the adsorbate at the adsorber inlet; (4) the ratio of the grain saturation time to the residence time of a grain in the front zone; and (5) the Peclet number, composed of the filtration rate, specific size of the filtration area (grain radius or half-width of gaps between sheets), and molecular diffusion coefficient. The values of these criteria change with modification of the tortuosity of transport nanopores. Simple mathematical analysis has shown that the adsorber volume decreases in proportion to the decrease in the nanopore tortuosity induced by bed-structure regularization. The pressure drop through the adsorber, as well as power consumption, will remain unchanged. ┬й 2007 Allerton Press, Inc.
