摘要
利用X射线衍射、热重分析、红外光谱、元素分析、四组分和气相色谱等手段研究热解气氛和温度对固体残渣和页岩油气的产率及组成的影响。结果表明有氧气氛中油页岩能够在较低的外部温度下发生热解,空气气氛中350℃时的页岩油产率可达到Fisher含油率的51%,为氮气气氛下的3.5倍,且提高了页岩油品质量;气氛和温度是油页岩热解的关键影响因素,有氧气氛在油页岩的开发利用中潜力巨大。
The influences of atmosphere and temperature on solid residue,shale oil and gas,as well as yields of shale oil and compositions of shale oil and gas were investigated by XRD,TG,FT-IR,elemental analysis,four components analysis and GC-MS.The results show that the pyrolysis of oil shale can occur at a lower external temperature in oxidative atmosphere.Shale oil yield can reach 51%of Fisher assay oil content at 350℃in air,which is 3.5 times higher than that in nitrogen.And the quality of shale oil is improved.It is also found that atmosphere and temperature are the key factors affecting oil shale pyrolysis,and oxidative atmosphere has a great potential in the development and utilization of oil shale.
