We are making use of an EPR technique developed in this lab to determine the pore size and number distribution in high volatile bituminous coal using nitroxide spin probes I-IX of different sizes, shapes, and reactivity. This year, we have studied pore size and shape distribution in Pittsburgh No. 8 (Argonne Premium Coal sample (APCS) No. 4), Blind Canyon (APCS No. 6), and Illinois No. 6 (APCS No. 3) coal from the Argonne Premium Coal Program as well as in PSOC-311 (No. 6 seam, Fruitland, New Mexico) and PSOC-1354 (Illinois No. 6, Douglas County, IL) coals. These coals were examined because independent studies related to pore size and shape distribution have recently been reported. We have also reported a study of the acidic and phenolic site distribution in Black Creek (Alabama) and APCS No. 3 coal samples finding that these sites exceed the amine site. It was also shown that the presence of hydrogen bonding did not aid the incorporation of spin probes in Mary Lee (Alabama) and Black Creek (Alabama) Coal. 5 figs., 2 tabs.
