Advanced NMR-Based Techniques for Pore Structure Analysis of Coal. Quarterly Report No. 7, April 1, 1993--June 31, 1993
Description:
One of the main problems in coal utilization is the inability to properly characterize its complex pore structure. Coals typically have micro/ultramicro pores but they also exhibit meso and macroporosity. Conventional pore size techniques (adsorption/condensation, mercury porosimetry) are limited because of this broad pore size range, microporosity, reactive nature of coal, samples must be completely dried, and network/percolation effects. Small angle scattering is limited because it probes bot…
