Abstract Vanadyl porphyrins were isolated from Yakutiya oil shale bitumens and also from kerogen and bitumen pyrolysates. They were analysed by mass spectrometry, HPLC and 1 H NMR. The oil shales investigated were all from the same formation (Cambrian) but from samples containing different kerogen types. Samples ranged in maturity from R o = 0.5 to 0.7. Bitumens extracted from the shales, with a value of R o = 0.5 contained mainly DPEP porphyrins, that is chlorophyll α (C 31 D and C 32 D) and… CONTINUE READING
