[...]... effective and reliable methods to measure pure gas and gas mixture adsorption equilibria; preventing young (and old) experimenters from doing all the mistakes we have done during our laboratory work*); making experimental gas adsorption data measured today in many laboratories all over the world more easily comparable to each other, as methods and procedures should be come more and more similar and possibly... specifications and environmental conditions As gas adsorption equilibria data up to now cannot be calculated accurately by theoretical or analytical simulation based models, it is necessary to measure them, i e to determine them by reliably and accurately performed experiments The purpose of this book is to present a) classical and new experimental methods to measure adsorption equilibria of pure gases and gas. .. porous solids, and 2 b) adsorption isotherms for data correlation allowing to calculate gasadsorption -equilibria data at other gas concentrations, pressures and temperatures These data and correlation functions are needed in simulation programs to develop and check new or better, i e smaller, faster and more energyefficient adsorption based processes for a large variety of engineering, health and environmental... PREFACE This book is intended to present for the first time experimental methods to measure equilibria states of pure and mixed gases being adsorbed on the surface of solid materials It has been written for engineers and scientists from industry and academia who are interested in adsorption based gas separation processes and/ or in using gas adsorption for characterization of the porosity of solid materials... world, it is to be expected that adsorption as a separation technology for gaseous (and liquid) mixtures will be of growing importance and impact to chemical, biochemical and environmental technology as well as to other fields of sciences (medicine, pharmacy) and engineering EXPERIMENTAL METHODS 3 Gas adsorption equilibria can be measured by several basically different methods In this section we are... styling of the manuscript and for several encouraging e-mails and notes Siegen - Weidenau Leipzig J U Keller R Staudt INTRODUCTION Abstract This introductory chapter provides some background information of the material to be presented: experimental methods to measure adsorption equilibria of pure and mixed gases on inert porous solids Applications of gas adsorption processes in science and technology are... methods for gas adsorption equilibria which are presented in this book are outlined Several other phenomena in gas adsorption systems like the kinetics of the mass exchange process, which could not be considered here are mentioned in brief in Section 4 There also some general information on gas adsorption systems will be given and references for the various fields mentioned will be provided 2 GAS ADSORPTION. .. collaboration of a theoretician (JUK) and an experimentalist (RS) over more than twelve years in the field of gas adsorption systems at the Institute of Fluid- and Thermodynamics (IFT) at the University of Siegen, Siegen, Germany This collaboration resulted in the development of several new methods to measure not only pure gas adsorption, but gas mixture or coadsorption equilibria on inert porous solids... concepts of mass and – to a lesser extent – volume of a sorbed phase are discussed in Sect 5 In Sect 6 a short overview of the Chapter 1 18 experimental methods used to measure adsorption equilibria and enthalpies of pure and mixed gases in rigid and swelling sorbent materials is given In view of space limitations we have to restrict the discussion to classical methods like volumetry/manometry and gravimetry... the drift of the balance Useful information on measurement methods of standard thermodynamic parameters like temperature, pressure, density of gases etc can be found in the literature [0.27, 0.28] Thermal equations of state (EOS) of pure gases and gas mixtures are represented in [0.29-0.30] The standard method to measure pure gas adsorption equilibria most often used today is the volumetric or manometric . alt="" GAS ADSORPTION EQUILIBRIA Experimental Methods and Adsorptive Isotherms This page intentionally left blank GAS ADSORPTION EQUILIBRIA Experimental Methods. to the development of effective and reliable methods to measure pure gas and gas mixture adsorption equilibria; preventing young (and old) experimenters from
