OSTI ID:5568429
The objective of this work is to perform an NMR study of the aromaticity in coals, coal derived products and/or model compounds generated by pyrolysis and thermal solubilization of coal in the presence of a hydrogen donor solvent. Cross Polarization with Magic-Angle Spinning (CP/MAS) will be used to measure the carbon aromaticity, and Combined Rotation and Multiple Pulse Spectroscopy (CRAMPS) NMR techniques will be used to measure the hydrogen aromaticity. From these NMR measurements the aromatic hydrogen-to- carbon ratio will be obtained and used to study condensation/retrograde reactions during coal liquefaction. The study consists of the following tasks: develop NMR methods to determine aromatic carbon by CP/MAS and aromatic hydrogen by CRAMPS for low hydrogen containing organic solids such as coals, and coal residues; characterize the feasibility of applying the NMR methods for quantitative measurements in coals; and analyze selected samples of coals and coal-derived products to demonstrate applicability of the NMR methods to study-coal liquefaction. 5 refs., 7 figs., 1 tab.
