Structural analysis of Aleksinac oil shale kerogen by high-resolution solid-state 13C n.m.r. spectroscopy
Abstract
A sample of kerogen from Aleksinac oil shale was examined by high-resolution solid-state 13C n.m.r. spectroscopy. The presence and relative proportions of kerogen structural units were estimated using a combination of NQS and T1ρ{variant}C methods with a peak-synthesis technique applied to the 13C CP-MAS spectrum. Relaxation parameters from these experiments were used to estimate differences in relative 'mobility' of various structural units. The kerogen was found to be highly aliphatic and to contain ∼ 79% long-chain aliphatic plus alicyclic structures, as well as ∼ 9% aromatic structures. These findings are in good agreement with the characterization of the same kerogen from its oxidation products. © 1995.
