Abstract

"In this work novel porous adsorbent media having partially fractal structures and stratified packed-beds are constructed and their dynamic performance with respect to their adsorptive capacity through the construction and solution of rigorous models is studied. The results show that conventional columns packed with partially fractal porous adsorbent particles provide larger breakthrough times and dynamic utilization of the adsorptive capacity of the column when compared with those of conventional columns employing conventional adsorbent particles which do not possess a partially fractal structure. Furthermore, stratified column beds exhibit superior species separation performance than conventional columns when they are packed with either conventional or partially fractal porous adsorbent media, and their highly desirable separation performance is increased further when the spatial ligand density distribution in the adsorbent particles is non-uniform and is described by certain functional forms. The stratified columns packed with partially fractal porous adsorbent media provide to the designer and user of chromatographic column systems, especially in preparative and process chromatography, more degrees of freedom with respect to the number of variables and parameters that could be controlled in the design, construction, and operation of efficient chromatographic adsorption separation systems. The models, porous media, and systems constructed in this work can also be extended into other relevant fields including chemical catalysis, biocatalysis, and membrane separations which employ porous media"--Abstract, page iv.
