Thermodynamics and surface structure of coals
We have reported the determination of the average micropore diameter of an Argonne Illinois No. 6 coal (77% C, daf) and a standard 15 A diameter Spherocarb sample by {sup 129}Xe NMR spectroscopy. We have successfully applied this technique to determine the average micropore diameter of the full series of Argonne coals. We have recently developed a computer program (Appendix A) which correlates the 129 Xe NMR spectrum of Coals directly to the micropore size distribution of each Argonne coal. The micropore size distribution of Argonne: Pocahontas No. 3 (91.8% C, dmmf); Pittsburgh No. 8 (85.0% C, dmmf); and Blind Canyon (81.3% C, dmmf) coals, determined by 129 Xe NMR spectroscopy are shown in Figures 2, 4, and 6, respectively.
