摘要：

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-degrees-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-degrees-C) and the high-temperature (420-650-degrees-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.
