Book Description
Un procédé d’adsorption–électrodésorption sur textile de carbone activé est proposé afin de répondre à la problématique des composés organiques volatils à l’état de traces dans les gaz à fort potentiel énergétique : biogaz et gaz de ville. Une approche expérimentale en deux parties a été conduite afin de premièrement, sélectionner le matériau adéquat dans les conditions opératoires considérées et modéliser les phénomènes physico-chimiques relatifs à l’adsorption et la désorption thermique, deuxièmement, mettre en oeuvre ce matériau dans une unité pilote de purification en continu, à l’échelle du laboratoire. Un échantillon représentatif de COV est retenu : toluène, isopropanol, dichlorométhane, éthanethiol, octaméthylecyclotétrasiloxane et tétrahydrothiophène. L’adsorption et la désorption de ces composés sur différents textiles de carbone activé sont caractérisées, modélisées et quantifiées afin de pouvoir dimensionner l’unité pilote de traitement en continu.

Book Description
'Adsorption Calculations and Modelling' provides readers with practical, useful information about how to make adsorption calculations and formulate models describing adsorption processes. Unlike most books on this subject, this book treats both gas phase adsorption and liquid phase adsorption with equal emphasis, and supplies a rigorous treatment of multi-component adsorption. It also covers adsorption applications in environmental applications including the use of impregnated adsorbents for protection against toxic gases and carbon adsorption in water and wastewater treatment.Explores the most up-to-date information on multicomponent adsorption Details adsorption applications in environmental application Explains the fundamentals of adsorption calculation in a simple, straightforward manner.

Book Description
Porous materials are of scientific and technological importance because of the presence of voids of controllable dimensions at the atomic, molecular, and nanometer scales, enabling them to discriminate and interact with molecules and clusters. Interestingly the big deal about this class of materials is about the “nothingness” within — the pore space. International Union of Pure and Applied Chemistry (IUPAC) classifies porous materials into three categories — micropores of less than 2 nm in diameter, mesopores between 2 and 50 nm, and macropores of greater than 50 nm. In this book, nanoporous materials are defined as those porous materials with pore diameters less than 100 nm.Over the last decade, there has been an ever increasing interest and research effort in the synthesis, characterization, functionalization, molecular modeling and design of nanoporous materials. The main challenges in research include the fundamental understanding of structure-property relations and tailor-design of nanostructures for specific properties and applications. Research efforts in this field have been driven by the rapid growing emerging applications such as biosensor, drug delivery, gas separation, energy storage and fuel cell technology, nanocatalysis and photonics. These applications offer exciting new opportunities for scientists to develop new strategies and techniques for the synthesis and applications of these materials.This book provides a series of systematic reviews of the recent developments in nanoporous materials. It covers the following topics: (1) synthesis, processing, characterization and property evaluation; (2) functionalization by physical and/or chemical treatments; (3) experimental and computational studies on fundamental properties, such as catalytic effects, transport and adsorption, molecular sieving and biosorption; (4) applications, including photonic devices, catalysis, environmental pollution control, biological molecules separation and isolation, sensors, membranes, hydrogen and energy storage, etc./a
