AB  - The chemical nature of the kerogen from Aleksinac (Yugoslavia) oil shale was studied by thermal analysis of a kerogen concentrate and the partially degraded kerogen concentrates obtained as intermediates in its stepwise alkaline permanganate oxidation. The initial kerogen concentrate decomposed in the range 200-550°C and the DTG profile consisted of several overlapping peaks. The partially degraded kerogen concentrates were thermally more stable. Their thermograms consisted of two distinct parts: the low- (150-420°C) and the high-temperature (420-650°C) part. Each of them was complex, involving two or more components. On the basis of IR data, it was suggested that the low-temperature part corresponded to the thermal degradation of aliphatic, and the high-temperature part to the degradation of aromatic components.
AB  - Mittels Thermoanalyse eines Kerogenkonzentrates und als Zwischenprodukte einer schrittweisen alkalischen Permanganatoxidation erhaltener, teilweise abgebauter Kerogenkonzentrate wurde die chemische Natur von Kerogen eines Ölschiefers aus Aleksinac (Jugoslawien) untersucht. Das ursprüngliche Kerogenkonzentrat zersetzt sich im Bereich 200–550°C, die DTG-Kurve besteht aus mehreren überlappenden Peaks. Die teilweise abgebauten Kerogenkonzentrate waren thermisch stabiler. Ihre Thermogramme gliedern sich in zwei Teile: in den Niedrig- (150–420°C) und in den Hochtemperaturbereich (420–650°C). Alle waren komplexer Natur, bestehend aus zwei oder mehr Komponenten. IR-sUntersuchungen lassen darauf schließen, daß der Niedrigtemperaturbereich dem thermischen Abbau der aliphatischen, der Hochtemperaturbereich hingegen dem Abbau der aromatischen Bestandteile entspricht.

AB  - 13C NMR spectroscopy was applied in the investigation of the structure of the organic matter in oil shales. By using Proton Enhanced Nuclear Induction Spectroscopy, a fair resolution of aliphatic and aromatic carbon signals was achieved. This method provided information on the relative ratio of aliphatic and aromatic carbons within a given set of samples (Aleksinac, Kimmeridge, Colorado, Australian torbanite and Estonian kukersite). © 1978.
