The adsorption and diffusion of N2, O2, CO2, CH4 and C2H6 in studied by chromatographic method. Unlike most adsorptive separations the selectivity of the selected gases in the micropores of the sieve. Analysis were caried out on the response curve of a pulse of sample gas injected into a stream of helium carrier. The Henry's constant, K and the micropore diffusion, Dc/rc2 were evaluated from the first and second moment of the response curve while the activation energy, E was obtained from the Arrhenius plot.[Authors' abstract].

Equilibrium adsorption and diffusion data for oxygen, nitrogen, methane and argon in carbon molecular sieves 3A and 5A at 0C, 30C and 50C were obtained at pressures up to 13 Bar using a high-pressure Cahn electrobalance. On a molar basis, methane had the highest adsorption capacity among the four gases studied both in 3A and 5A molecular sieve carbons. Oxygen and nitrogen had approximately the same equilibrium adsorption capacity. Equilibrium adsorption data were represented by a Langmuir equation and the Vacancy Solution Model (VSM). The VSM appears to give a good fit of the experimental data while the representation of the experimental data by the Langmuir equation showed deviation, especially at high pressures. The isosteric heats of adsorption were found to increase slightly with an increase in surface coverage. The values were slightly higher on 3A than on 5A for all the gases except argon. Kinetic data showed that oxygen has the highest diffusion rate and methane the lowest. Diffusivities increased with temperature. Keywords: Adsorption; Diffusion rate; Molecular sieve carbons; Langmuir equation; Vacancy solution model; Kinetic data; Isotherm; Isosteric heat of adsorption. (JES).

The separation of a mixture into its individual components is one of the most fundamental procedures in analytical and industrial chemistry. This classic book in analytical chemistry provides a comprehensive yet systematic outline of all known separation methods. Through its detailed treatment of the basic principles of separation possibilities, it not only covers what is currently known, but also represents a treasure trove of methods that are still awaiting further development. It is clearly structured and contains interesting examples, further reading and a detailed index. An indispensable book for advanced students of natural sciences (chemistry, biochemistry, food chemistry, pharmacy, clinical chemistry, environmental sciences) and technology (chemical engineering, chemical-physical measurement & biotechnology), as well as teachers of these disciplines.

This book describes the tremendous progress that has been made in the development of gas separation membranes based both on inorganic and polymeric materials. Materials discussed include polymer inclusion membranes (PIMs), metal organic frameworks (MOFs), carbon based materials, zeolites, as well as other materials, and mixed matrix membranes (MMMs) in which the above novel materials are incorporated. This broad survey of gas membranes covers material, theory, modeling, preparation, characterization (for example, by AFM, IR, XRD, ESR, Positron annihilation spectroscopy), tailoring of membranes, membrane module and system design, and applications. The book is concluded with some perspectives about the future direction of the field.

This textbook discusses engineering principles relating to air pollution and greenhouse gases (GHGs); it focuses on engineering principles and designs of related devices and equipment for air emission control for a variety of industries such as energy, chemical, and transportation industries. The book aims primarily at senior undergraduate and graduate students in mechanical, chemical and/or environmental engineering departments; it can also be used as a reference book by technical staff and design engineers who are interested in and need to have technical knowledge in air pollution and GHGs. The book is motivated by recent rapid advances in air pollution and greenhouse gas emissions and their control technologies. In addition to classic topics related to air pollution, this book is also featured with emerging topics related to air pollution and GHGs. It covers recent advances in engineering approaches to the reduction of GHG emissions including, but are not limited to, green energy technologies and carbon sequestration and storage. It also introduces an emerging topic in air pollution, which is referred to as Nano Air Pollution. It is a growing concern in air pollution, but largely missing in similar books, likely because of recent rapid advances in nanotechnology has outpaced the advances in nano air pollution control.
