In order to provide a better characterization of the origin and volume of thermogenic gas generation hydrous pyrolysis (HP) experiments were performed on coals and shales at 330 and 360^oC for 72 hours. The maturity range of coals and shales used for HP varies from 0.57 to 0.92% R_o. The maturity increase caused by HP at 330 and 360^oC ranges from 1.32 to 1.39% and from 1.71 to 1.83%, respectively. δ¹³C of CH₄, C₂H₆, C₃H₆ and n-C₄H₁₀ in HP gases versus their reciprocal C-number have a concave relationship, and therefore do not follow a linear trend. δ²H of CH₄, C₂H₆ and C₃H₆ in HP gases versus their reciprocal H-number show both linear and convex-concave relationships. The growth of CO₂ yields during HP was higher for shales than for coals. H₂S yields from shales are higher than from coals, which can be connected with catalytic and adsorbed influence of shale matrix. H₂ was also generated in notable quantities from water and organic matter of coals and bigger amounts from shales. N₂ yields grow with the increase of R_o after 360^oC HP and it is more enriched in ¹⁵N isotope than after 330^oC.

为了更好地表征产热气体的来源和体积，在煤和页岩上进行了 330 和 360 ^o C 72 小时的含水热解 (HP) 实验。用于 HP 的煤和页岩的成熟度范围从 0.57% 到 0.92% R _o不等。HP 在 330 和 360 ^o C引起的成熟度增加范围分别为 1.32 至 1.39% 和 1.71 至 1.83%。CH ₄、C ₂ H ₆、C ₃ H ₆和n -C ₄ H _{10 的}δ ¹³ C在 HP 气体中与它们的倒数 C 数有一个凹的关系，因此不遵循线性趋势。HP 气体中 CH ₄、C ₂ H ₆和 C ₃ H _{6 的}δ ² H与其倒数 H 值显示线性和凸凹关系。在 HP 期间，页岩的 CO ₂产量增长高于煤。页岩的H ₂ S产率高于煤，这与页岩基质的催化和吸附作用有关。水和煤的有机质中也产生了大量的H _{2 ，}而页岩中也产生了大量的H ₂。N ₂360 ^o C HP后产量随着R _o的增加而增加，并且¹⁵ N同位素比330 ^o C后更富集。
