This book was released on 2013 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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, leaf iv.

Download or read book The Molecular Theory of Adsorption in Porous Solids written by Yury Konstantinovich Tovbin and published by CRC Press. This book was released on 2017-10-17 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the adsorption phenomenon the substances from the external environment the gas or liquid are absorbed by a solid surface (adsorbent). Adsorption is used to separate gaseous and liquid mixtures, for drying and purification of gases and liquids. This reference broadly explores the calculation of the equilibrium and dynamic characteristics of adsorption in porous bodies at the molecular level. Two new theories of statistical physics are presented, both developed by the author for the consistent description of the equilibrium distribution of molecules and dynamics of flows in complex porous materials to be able to solve a wide range of practical tasks in the development of new technologies.
Download or read book Adsorption Technology in Water Treatment written by Eckhard Worch and published by Walter de Gruyter. This book was released on 2012-08-31 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption processes have played a central role in water treatment for many years but their importance is on the rise with the continuous discoveries of new micropollutants in the water cycle (pharmaceuticals for example). In addition to the classical application in drinking water treatment, other application fields are attracting increasing interest, such as wastewater treatment, groundwater remediation, treatment of landfill leachate, and so on. Based on the author's long-term experience in adsorption research, the scientific monograph treats the theoretical fundamentals of adsorption technology for water treatment from a practical perspective. It presents all the basics needed for experimental adsorption studies as well as for process modelling and adsorber design. Topics discussed in the monograph include: introduction into basic concepts and practical applications of adsorption processes; adsorbents and their characterisation, single and multi-solute adsorption equilibria, adsorption kinetics, adsorption dynamics in fixed-bed adsorbers and fixed-bed adsorber design, regeneration and reactivation of adsorbents, introduction into geosorption processes in bank filtration and groundwater recharge. According to the increasing importance of micropollutants in the water cycle, particular attention is paid to their competitive adsorption in presence of background organic matter. Clear illustrations, extensive literature references and a useful index make this work indispensible for both scientists and technicians involved in water treatment.

Download or read book Equilibria and Dynamics of Gas Adsorption on Heterogeneous Solid Surfaces written by W.A. Steele and published by Elsevier. This book was released on 1996-12-17 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fact that the surfaces of real solids are geometrically distorted and chemically non-uniform has long been realized by the scientists investigating various phenomena occurring on solid surfaces. Even in the case when diffraction experiments show a well-organized bulk solid structure, the surface atoms or molecules will usually exhibit a much smaller degree of surface organization. In addition to the results obtained from electron diffraction, this can be seen in the impressive images obtained from STM and AFM microscopies. This geometric and chemical disorder is the source of the energetic heterogeneity for molecules adsorbing on real solid surfaces. Hundreds of papers have been published showing that this heterogeneity is a major factor in determining the behaviour of real adsorption systems.Studies of adsorption on energetically heterogeneous surfaces have proceeded along three somewhat separate paths, with only minor coupling of ideas. One was the study of adsorption equilibria on heterogeneous solid surfaces. The second path was the study of time evolution of adsorption processes such as surface diffusion or adsorption-desorption kinetics on heterogeneous surfaces, and the third was the study of adsorption in porous solids, or more generally, adsorption in systems with limited dimensions. The present monograph is a first attempt to provide a synthesis of the ways that surface geometric and energetic heterogeneities affect both the equilibria and the time evolution of adsorption on real solids. The book contains 17 chapters written by a team of internationally recognized specialists, some of whom have already published books on adsorption.

However, recent advances in chemical engineering in the fields of adsorption and porous bodies have now made it possible to estimate many of the design parameters with sufficient accuracy.The author of this book has worked on various aspects of adsorption from the viewpoint of basic phenomenology and applications to separation processes in chemical industry and environmental pollution control. He has written this book with the aim of establishing a basic chemical engineering methodology for adsorption process design. Throughout the book, activated carbon is used as the main example of adsorbent in the application of the methodology and principles, although topics on special adsorbent systems are also included to cover modern development of adsorption technology.
