Pore Structure Characterization of Coals & Chars Via NMR
Davis, P.J.; Smith, D.M.; Bartholomew, C.H.; White, W.E. and Hecker, W.C.
Twelfth Symposium of the Rocky Mountain Fuels Society, Denver, 1989. Funded by ACERC (National Science Foundation and Associates and Affiliates).
Due to the wide pore size range and complexity of coals and chars, it is difficult to study the pore structure. Multiple techniques such as gas adsorption, mercury porosimetry, and density measurements are often used. These techniques suffer from limited pore size range, pore shape assumption, network/percolation effects, and sample changes during analysis. To obtain a more complete description of coals and chars, NMR spin-lattice relaxation measurements of water saturated coals and chars have been performed. The NMR technique does not suffer from network/percolation effects, sample changes, pore shape assumption (rp>5nm). Three coals and their chars were compared.
