The article discusses the formation of diverse hydrocarbons in subsurface rocks through catalytic processes involving solid acids. Laboratory experiments demonstrated that these rocks play a crucial role in producing H and OH radicals via H2O dissociation, leading to the synthesis of various hydrocarbons. The study revealed that abiotic H2 and hydrocarbons can be generated irrespective of the presence of living organisms. By mixing solid acid-containing rocks with H2O and different carbon sources at varying conditions, researchers identified distinct hydrocarbon profiles up to C11, such as CH4 and aromatic/aliphatic hydrocarbons. This indicates the potential of rocks near hydrothermal vents or volcanic regions to facilitate the conversion of CO2 into CH4 with the assistance of H radicals. The findings shed light on the mechanisms behind hydrocarbon formation in rock particles, offering insights into the processes governing subsurface hydrocarbon production.
