不同介质条件下油页岩热解的初步研究

利用高压釜热解实验装置，对采自民和盆地的油页岩进行全岩、全岩加去离子水和全岩加碱性饱和KCl溶液等3个系列的热解实验研究，并对这3个系列生成的页岩气和页岩油进行对比分析。结果表明：介质的加入有利于液态物的产出，跟油页岩直接加热相比，去离子水的加入使得页岩油的平均产率从83.66 mg/g提高到210.15 mg/g，但是抑制页岩气的生成；而碱性饱和KCl溶液的加入对页岩油和页岩气都有贡献，使得页岩油平均产率从83.66 mg/g提高到186.16 mg/g，页岩气平均产率从7.56 mL/g增大到9.08 mL/g。

PRELIMINARY STUDY ON THE PYROLYSIS OF OIL SHALE UNDER DIFFERENT MEDIUMS

The pyrolysis of oil shale from Minhe Basin under three different medium conditions(shale retort,with deionized water and with alkalic saturated potassium chloride solution) was investigated using autoclave simulation device.The formation of shale oil and shale gas in the three-series was analyzed and compared.Test results show that as compared with shale retort,under aqueous medium more shale oil can be produced.With deionized water medium,the average yield of shale oil increases from 83.66 mg/g(shale retort case) to 210.15 mg/g,yet it seems to suppress the formation of shale gas;in alkalic saturated potassium chloride medium,both average yields of shale oil and shale gas go up,the former increases form 83.66 mg/g to 186.16 mg/g and the latter increases from 7.56 mL/g(shale retort case) to 9.08 mL/g.
