Carbon-13 NMR study of separated coal macerals. Final report, September 1, 1982-August 31, 1985

Technical Report ·
OSTI ID:5723312
The objectives of this program are: (1) to continue our previous contract efforts to perform petrographic analysis of whole coals and to separate the several maceral groups of various rank by density gradient centrifugation methods; (2) separate macerals such as fusinite, semi-fusinite, sporinite, etc. from coals that have relatively high concentrations of these macerals in addition to the more common vitrinite maceral; (3) employ multiple pulse spectral techniques to obtain greater structural details; (4) compare various structural features in macerals and maceral groups vis-a-vis rank and other properties. 2 figs.
