摘要
采用热液对顶砧压腔装置,对高温高压水中干酪根和沥青质的热解过程进行了原位观测。结果发现干酪根和沥青质在高温高压水中的热解行为存在很多的差别:干酪根不溶于高温高压水中,并保持固相状态直到发生异相降解反应,生成的小分子的液相和气相烃类化合物能够与高温高压下的水混溶,而当温度降低后这些烃类物质则从水中析出;沥青质在高温高压下首先与水混溶,混溶后随着温度和压力的继续升高发生降解反应,最终生成类似石墨结构的碳物质。
The in situ visualization of pyrolysis of kerogen and asphalt in high-temperature and high-pres- sure water studied by hydrothermal anvil cell. The phenomena of these two matter present great different. Kerogen pyrolyzes to liquid and gas phase hydrocarbon compounds in an inhomogeneous form at high temperature and high-pressure. These hydrocarbon compounds dissolve in water at high temperature and highpressure and separate out during the decrease of temperature to the ambient temperature. Asphalt dissolves in water at high temperature and high pressure firstly, with increasing temperature further, it finally reactions with water to form graphite-soot matter.
