Abstract

Twelve hydrothermal experiments were conducted with Domanik oil shale from the Ukhta region (Chut River) at temperatures of 250–375 °C and periods of 24 hours (6 experiments), 72 hours (5 experiments), and 48 hours (1 experiment). The composition of hydrocarbon gases C₁–C₅ was studied for each experiment and quantitative data on their yields were obtained. Based on these data, the kinetic spectra of individual gases C₁–C₅ were established under hydrothermal experiment conditions. The character of the kinetic spectra of individual alkanes C₂–C₅ is virtually identical; their main narrow maximum corresponds to Ea 55 kcal/mol with an Arrhenius factor of 1×10¹⁴ s^-1. The distribution of the methane generation potential by activation energies is distinguished by the fact that a significant part of its generation potential falls within the region of activation energies of 60–70 kcal/mol and by the uncertainty of the distribution character in this region.
