PROTON NMR IMAGING STUDIES OF COAL USING DEUTERATED SOLVENTS

摘要

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.
