摘要:

分别将蒙脱石、伊利石、高岭石和硫酸锰与干酪根充分混合后,在高压反应釜进行了压力为100 MPa、200 MPa的热解,并将热解产物在Wasson\|ECE Agilent 6890气相色谱仪中进行了分析,结果表明:粘土矿物和无机盐在干酪根的热解生烃过程中具有不同的影响,其中,高岭石对气态烃的生成有一定的促进作用,而硫酸锰、伊利石、蒙脱石则表现为抑制生烃的作用;压力能提高粘土矿物和无机盐的催化活性,表现为高压增加了气态烃的产率,当压力增加到200 MPa时,蒙脱石的催化能力提高最为明显,而高岭石的则最小。认为压力对粘土矿物催化生烃的影响是由于矿物质本身结构的差异和压力对各矿物结构作用的强弱所造成。

关键词: 压力, 粘土矿物, 气态烃

Abstract:

Kerogen was mixed with montmorillonite, illite, kaolinte, manganese sulfate, and the samples were put into gold\|tubes, welded. Then gold\|tubes in a stainless steel autoclave were pyrolyzed under 100MPa and 200MPa conditions. The quantification of pyrolyzate analysis was performed through Wasson\|ECE Agilent 6890 gas chromatography. The results show that catalytic clays have different effects in the process of pyrolysis and hydrocarbon generation. Kaolinte has a positive effect on hydrocarbon gaseous generation, however, montmorillonite, illite and manganese sulfate retard the generation of hydrocarbon. Pressure can enhance the catalytic activity of catalytic clays, the yields of hydrocarbon gaseous are increased with pressure. At the level of 200 MPa, it is most obviously for montmorillontie to improve the catalytic activity, but kaolite is little. The influence of pressure on clay\|catalytic hydrocarbon generation comes from the difference of clay mineral structure and its respons to pressure.

Key words: Pressure, Clay mineral, Gaseous hydrocarbon.
