摘要

Natural vanadyl (VO~2+)--deoxophylloerythroetioporphyrins (DPEP) are shown to be capable of reacting and quantitatively incorporating into the immature kerogen model materials (torbanite, lignites, subbituminous coal and an immature lacustrine kerogen) at 200deg.C for 72 h in the absence/presence of air oxygen. Electron spin resonance is used to monitor the incorporation of VO~2+ -DPEP into the kerogen models. The products of the incorporation resemble natural kerogen enriched with VO~2+ --DPEP. The simulation experiments described in this paper clearly show that the kerogen VO~2+ -P may originate from VO~2+ -DPEP incorporation into the kerogen macromolecular structures during catagenesis.
