%X Natural vanadyl (VO2+)-deoxophylloerythroetioporphyrins (DPEP) have been shown to be capable of reacting and quantitatively incorporating into immature kerogen model materials (torbanite, lignites, subbituminous coal and immature lacustrine kerogen) at 200ˇăC for 72 h in the absence/presence of air. Electron spin resonance was used to monitor the incorporation of VO2+-DPEP into the kerogen models. The products of the incorporation resemble natural kerogen enriched with VO2+. The simulation experiments described in this paper clearly show that the kerogen VO2+-P may originate from VO2+-DPEP incorporation into the kerogen macromolecular structures during catagenesis.
