Proton NMR imaging studies of coal using deuterated solvents
Solvent transport into coal was studied by proton NMR imaging using pyridine - d(5) and acetone - d(6). Solvent swelling of Fushun bituminous coal was also observed by proton spin density images. From these NMR images, some information on the transport and swelling behavior of coal was obtained.
