All experimental results ofcarbon-containing materials-FkO systems at high pressure and temperature indicate that H2O participates in the hydrocarbon formation reactions, which provides hydrogen to form hydrocarbons and provides oxygen for CCh.

• 气相色谱分析结果表明，含碳物质与水(含水矿物)在高温高压下反应，均生成了以CH_4为主的烃类气体，并伴有CO_2等，表明H_2O可参与成烃反应，为烃类形成提供氢源，为CO_2形成提供氧源。
