The Molecular Theory of Adsorption in Porous Solids


Book Description

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.

Adsorption by Powders and Porous Solids


Book Description

The declared objective of this book is to provide an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. The primary aim is to meet the needs of students and non-specialists who are new to surface science or who wish to use the advanced techniques now available for the determination of surface area, pore size and surface characterization. In addition, a critical account is given of recent work on the adsorptive properties of activated carbons, oxides, clays and zeolites. - Provides a comprehensive treatment of adsorption at both the gas/solid interface and the liquid/solid interface - Includes chapters dealing with experimental methodology and the interpretation of adsorption data obtained with porous oxides, carbons and zeolites - Techniques capture the importance of heterogeneous catalysis, chemical engineering and the production of pigments, cements, agrochemicals, and pharmaceuticals




Characterization of Porous Solids II


Book Description

The Second IUPAC Symposium on the Characterization of Porous Solids (COPS-II) provided the opportunity for detailed discussion and appraisal of the most important techniques currently used for the characterization of porous materials, especially those of technological importance. The 82 selected papers and reviews contained in this volume are mainly concerned with the theoretical and experimental aspects of adsorption, fluid penetration, small-angle scattering and spectroscopic methods with their application in the study of adsorbents, catalysts, constructional materials, etc. Particular attention is given to the characterization of carbons, oxides, zeolites, clays, cement and polymers. The wide range of materials and techniques described in this book provide a useful and comprehensive reference source for academic and industrial scientists and technologists.




Characterization of Porous Solids III


Book Description

The objectives of the Third IUPAC Symposium on the Characterization of Porous Solids (COPS-III) were (1) to provide the opportunity for specialists to exchange ideas and new information on theoretical principles and methodology and (2) to generate proposals for the comparison and utilization of the many techniques now available for the characterization of porous solids. A successful outcome of the Symposium has been the final report of the IUPAC Subcommittee on Recommendations for the Characterization of Porous Solids, a summary of which is given in these proceedings. The edited papers included in the present volume have been selected from the 155 oral and poster presentations given at this symposium, which attracted 200 participants from 28 different countries. The following topics were discussed:1. Simulation and modelling of pore structures and pore-filling mechanisms2. Novel experimental techniques with particular reference to high-resolution techniques3. Model pore structures and reference materials4. Porous materials of technological importance.The wide range of materials and techniques described provide a useful and comprehensive reference source for academic and industrial scientists and technologists.




Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density


Book Description

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.

Porous Materials


Book Description

This book is written in honor of Prof. Francisco Rodriguez-Reinoso, who has made significant contributions in the area of porous materials such as active carbons and graphenes. It details the preparation of porous materials, including carbonaceous, zeolitic, and siliceous materials, MOFs, aerogels, and xerogels, describing the characterization techniques and the interpretation of the results, and highlighting common errors that can occur during the process. This book subsequently presents the use of modeling based on thermodynamics to describe the materials. Lastly, it illustrates a number of current environmental protection applications in the context of both water and air.




Recent Advances in Gas Separation by Microporous Ceramic Membranes


Book Description

This book is dedicated to the rapidly growing field of microporous ceramic membranes with separating layers of pore diameter less than 2nm. The chapters of this book bring forward a wide range of issues, namely fundamentals of complex sorption and transport processes in micropore structures, highly innovative methods of preparation of microporous membranes and examples of their possible commercial applications. This book presents insights by distinguished investigators, who have contributed significantly to the advance of research efforts in the diverse topics described herein. Recently, significant progress has been made with respect to the development of novel microporous asymmetric membranes, mainly involving modification by means of deposition of additional material within the pores of the substrates. Most state-of-the-art technologies aiming in the development of microporous ceramic membrane are presented in the third section of the book. These include several material deposition methods and techniques on macroporous or mesoporous supports and substrates from the liquid or vapour phase, namely those involving sol-gel, zeolite and chemical vapour deposition techniques. In addition to the above-mentioned methods, the classical technique of carbonizing polymeric deposits along with one of the novel techniques of plasma-treating, organically deposited Langmuir-Blodgett films, are also presented. Nanophase mixed ionic-electron membranes for enhanced oxygen transport are described, which pose a strong candidacy for a number of significant commercial applications.
