Book Synopsis Diffusion in Nanoporous Materials, 2 Volumes by : Jörg Kärger
Download or read book Diffusion in Nanoporous Materials, 2 Volumes written by Jörg Kärger and published by John Wiley & Sons. This book was released on 2012-10-29 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atoms and molecules in all states of matter are subject to continuous irregular movement. This process, referred to as diffusion, is among the most general and basic phenomena in nature and determines the performance of many technological processes. This book provides an introduction to the fascinating world of diffusion in microporous solids. Jointly written by three well-known researchers in this field, it presents a coherent treatise, rather than a compilation of separate review articles, covering the theoretical fundamentals, molecular modeling, experimental observation and technical applications. Based on the book Diffusion in Zeolites and other Microporous Solids, originally published in 1992, it illustrates the remarkable speed with which this field has developed since that time. Specific topics include: new families of nanoporous materials, micro-imaging and single-particle tracking, direct monitoring of transient profiles by interference microscopy, single-file diffusion and new approaches to molecular modeling.

Book Synopsis Adsorption Technology in Water Treatment by : Eckhard Worch
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.

Book Synopsis The Molecular Theory of Adsorption in Porous Solids by : Yury Konstantinovich Tovbin
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 571 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.
Book Synopsis Recent advances in porous adsorbent assisted atmospheric water harvesting: a review of adsorbent materials by : Shuai Zhang
Download or read book Recent advances in porous adsorbent assisted atmospheric water harvesting: a review of adsorbent materials written by Shuai Zhang and published by OAE Publishing Inc.. This book was released on 2023-02-23 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water shortage is an increasing threat to humankind. Porous sorbent assisted atmospheric water harvesting (psaAWH) has emerged as an effective technological countermeasure. In this review, we summarize the types of porous adsorbents used in psaAWH and provide an overview of their states of development. The water adsorption mechanism and the processes associated with each material are analyzed, and the application prospects of the adsorbents are evaluated. The effect of the inherent properties (pore size, functional group, etc.) of the adsorbent on the water harvesting performance is also discussed. Further, we focus on the water adsorption/desorption kinetics of the adsorbents and outline various methods to improve the kinetics. At this stage, there are many strategies for improving the kinetics of the adsorbent, which in turn influences the adsorption process and intra/inter-crystalline diffusion. However, there is still limited research on the transport of water molecules in microporous adsorbents for psaAWH. Thus, this aspect is re-examined herein from a new perspective (superfluidity) in the review. Based on the discussion, we can reasonably infer that water molecule superfluidity can exist in nanoconfined channels, thus promoting the rapid transport of water molecules. The formation of water superfluidity is a feasible strategy for improving the intracrystalline diffusion of the psaAWH adsorbent. Finally, we consider the future developments and challenges of psaAWH in detail. We think this review can serve as a guide for further research in this ever-expanding field.

This conference was organized completely under the auspices of the International Adsorption Society. It was attended by 196 participants from 24 countries. Members of the Scientific Advisory Board, together with the Conference Committee, selected papers for presentation from a large number of proposals involving an especially high level of international participation. The fundamental aspects of adsorption is a subject which has grown rapidly in recent years, drawing researchers from many disciplines including materials science, chemistry, physics, biochemistry and biotechnology, and chemical, civil, mechanical and environmental engineering. Fundamentals of Adsorption serves as an excellent reference and may be used as a primary text for a graduate level course on adsorption research or as a secondary text for a course on any of the disciplines mentioned above.
Book Synopsis Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density by : S. Lowell
Download or read book Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density written by S. Lowell and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest in newly developed porous materials has prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. One might consider this new book as the 4th edition of "Powder Surface Area and Porosity" (Lowell & Shields), but for this new edition we set out to incorporate recent developments in the understanding of fluids in many types of porous materials, not just powders. Based on this, we felt that it would be prudent to change the title to "Characterization of Porous Solids and Powders: Surface Area, Porosity and Density". This book gives a unique overview of principles associated with the characterization of solids with regard to their surface area, pore size, pore volume and density. It covers methods based on gas adsorption (both physi and chemisorption), mercury porosimetry and pycnometry. Not only are the theoretical and experimental basics of these techniques presented in detail but also, in light of the tremendous progress made in recent years in materials science and nanotechnology, the most recent developments are described. In particular, the application of classical theories and methods for pore size analysis are contrasted with the most advanced microscopic theories based on statistical mechanics (e.g. Density Functional Theory and Molecular Simulation). The characterization of heterogeneous catalysts is more prominent than in earlier editions; the sections on mercury porosimetry and particularly chemisorption have been updated and greatly expanded.

Book Synopsis New Developments in Adsorption/Separation of Small Molecules by Zeolites by : Susana Valencia
Download or read book New Developments in Adsorption/Separation of Small Molecules by Zeolites written by Susana Valencia and published by Springer Nature. This book was released on 2021-01-04 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume compiles and discusses the fundamental and multidisciplinary knowledge on adsorption and separation processes using zeolites as adsorbents. Over the last decade, a large amount of research has been carried out for the development of zeolites as adsorbents. However, there is still a growing interest to increase the understanding of such selective adsorbents. Therefore, synthesis strategies and new approaches for developing new selective zeolite adsorbents for gas separation are presented in the first chapter. In addition, a chapter focused on adsorption characterization techniques of microporous materials is included. This will be helpful for advanced readers, since the new IUPAC recommendations for microporous characterization are not still widely employed by the zeolite community. Experimental and theoretical aspects of economically and environmentally relevant separations, which have been successfully carried out with zeolites, are discussed in detail in subsequent chapters. Finally, industrial zeolite based adsorption and separation processes as well as current perspectives for new zeolite based separations, and improvements of current technologies are presented.
