- Abstract
Thermodynamic simulation of the system living matter (algae, zooplankton, or green plants) + mineral matter (25% carbonates + 75% clay minerals) + standard seawater at temperatures and pressure corresponding to diagenesis indicates that kerogen can be synthesized, together with hydrocarbons and carbon dioxide, in the reaction mix. The removal of CO(g) and N(g) from the system is favorable for the reaction ΔCHO (s; H/C = 0.99, O/C = 0.041) → ΔCHO (s; H/C = 0.53, O/C = 0.055) + xСH(aq) + yCO(aq) + zHO, whose constant and stoichiometric coefficients were calculated based on the simulation results. It is demonstrated that a pressure increase is favorable, while a temperature increase is not, for the procedure of this reaction at P-T parameters of diagenesis: log K =-567 (20°C, 35 bar), 1170 (20°C, 200 bar),-1530 (20°C, 60 bar), and +1030 (20°C, 600 bar).
