| Popis: | Review of previous use of Gas-Solid Chromatography to the determine thermodynamics of coal adsorption revealed several problems with data acquisition, as discussed previously (quarterly report 6, January 1, 1991 to March 31, 1991). In addition, in previous studies, the effect of diffusion of the adsorbate into the coal was not correctly taken into account. The goal of the present work is to obtain a more complete characterization and understanding of the adsorbate/coal interaction from both a physical and chemical viewpoint. These studies should contribute much to the fundamental understanding of the interaction of technologically important molecules with the complex structure that is coal. In addition, this work has profound implications for modelling of various industrial processes, including: extraction of fuel from coal and from carbonaceous/inorganic matter in general, reaction of solvents with coal during production of clean coal and during production of organic chemicals from coal, effects of solvent swelling on coal structure and chemistry, and characterization of coal thermodynamics for efficient burning of coal. |
