Smith, D M

Work during the past quarter involved: (1) surface area measurement; (2) mercury porosimetry; (3) NMR pore structure analysis; and (4) diffusion measurements. Surface area measurements via both nitrogen and carbon dioxide adsorption were completed for all group A coals. Four particle sizes of three coals were studied with mercury porosimetry. NMR relaxation experiments were used to determine continuous pore size distributions. Activity concerning diffusion measurements has been in the area of improving experimental design for both the pellet string reactor and batch desorption experiments. 1 ref.
