Adsorption of dilute acetone and toluene on various types of commercial activated carbons were mearsured under chromatographic conditions, based on a linear isotherm assumption. Chromatographic pulse responses were analyzed by the method of moment in order to determine adsorption equilibrium constants and adsorption rate constant at the temperature within the range of 50-250 C. The selected commercial activated carbons were devided into 3 groups: activated carbons from coconut shell (YAOs), commercial activated carbon (LP814) and carbon molecular sieves (CMSs). At a given temperature, toluene vapor was preferably adsorbed on all types of activated carbons than acetone vapor. The adsorption equilibrium constants depended on the specific surface area and the surface characteristic of the activated carbons. YAOs with high specific surface, result high values of adsorption equilibrium constants. In addition, the hydroxyl on YAO4/8 surface enhanced the adsorbed amount of acetone vapor but reduced the adsorption of toluene. The adsorption on CMSs depended on the average pore diameters and the sizes of the adsorbate molecule. The rate of adsorption for both toluene and acetone were dependent of temperature, corresponding to Arrhenius equation. The heats of adsorption of both vapors were about 3 times heat of condensation, except the heats of adsorption of toluene on YAO4/8 which were less than heat of condensation.

This report reviews the Army's evaluation of carbon filters for use in the baseline incineration PAS, as well as the Army's change management process (the Army's tool for evaluating major equipment and operational changes to disposal facilities). In preparing this report, members of the Stockpile Committee evaluated exhaust gas emissions testing at the two operating baseline incineration systems, JACADS and the TOCDF; evaluated the development of the dilute SOPC carbon filter simulation model; and evaluated the conceptual design of a modified PAS with an activated carbon filter. The two major risk assessments conducted for each continental disposal site that use the baseline system, namely, (1) the quantitative risk assessment, which evaluates the risks and consequences of accidental agent releases, and (2) the health risk assessment, which evaluates the potential effects of nonagent emissions on human health and the environment, were also examined.

Adsorption promises to play an integral role in several future energy and environmental technologies, including hydrogen storage, CO removal for fuel cell technology, desulfurization of transportation fuels, and technologies for meeting higher standards on air and water pollutants. Ralph Yang's Adsorbents provides a single and comprehensive source of knowledge for all commercial and new sorbent materials, presenting the fundamental principles for their syntheses, their adsorption properties, and their present and potential applications for separation and purification. Chapter topics in this authoritative, forward-looking volume include: - Formulas for calculating the basic forces or potentials for adsorption - Calculation of pore-size distribution from a single adsorption isotherm - Rules for sorbent selection - Fundamental principles for syntheses/preparation, adsorption properties, and applications of commercially available sorbents - Mesoporous molecular sieves and zeolites - ̧-complexation sorbents and their applications - Carbon nanotubes, pillared clays, and polymeric resins Yang covers the explosion in the development of new nanoporous materials thoroughly, as the adsorption properties of some of these materials have remained largely unexplored. The whole of this book benefits from the new adsorbent designs made possible by the increase in desktop computing and molecular simulation, making Adsorbents useful to both practicing laboratories and graduate programs. Ralph Yang's comprehensive study contributes significantly to the resolution of separation and purification problems by adsorption technologies.
