Abstract: The main industrial utilization of oil shale is to produce shale oil through a retorting process. In order to lower the carrier gas temperature so as to prolong the service life of the carrier gas preheater and to save energy，moderate amount of oxygen was added to the carrier gas in the oil shale retorting process. The retorting process of oil shale under aerobic condition with low-temperature carrier gas was studied. The characteristic via increasing bed temperature in the retorting process was investigated. Gas and liquid products obtained from the retorting process under aerobic condition were compared with that under anaerobic condition. The results show that oxygen content in the carrier gas has a significant effect on the retorting process as temperature increasing. The temperature of oil shale bed can be increased and sustained to a high enough level for retorting process due to the heat generated by the oxidation reaction of oil shale. The oil yield and the main components content of shale oil under aerobic condition is close to those under anaerobic condition although light components and compounds contained O—H bond and C==O bond in shale oil under aerobic condition are little more than those under anaerobic condition. The results obtained from the present work provide a new retorting process of oil shale to produce shale oil，which has a better industrial application potential.

Key words: oil shale, shale oil, retorting under aerobic condition with low-temperature carrier gas, heat carrier gas

摘要： 油页岩干馏生产页岩油是油页岩的主要加工利用方式。为降低油页岩干馏所需热载气温度，以延长载气预热器使用寿命并实现节能操作，本文向热载气中掺入一定比例氧气，对含氧低温载气情况下的油页岩干馏过程进行了研究。测定了油页岩在含氧气体氛围中热解时的反应器床层升温特性，对气液相产物组成进行了分析并与无氧干馏产物进行了比较。结果表明，含氧低温载气干馏过程能够通过载气中的氧气与油页岩反应产生的热量使油页岩达到其干馏所需要的温度，页岩油收率及其成分与无氧高温载气干馏过程接近、而轻组分含量更高，并且含有更多的具有O—H键和C==O键官能团的化合物。本文研究结果为油页岩干馏生产页岩油提供了一种新的技术方法，具有较好的工业应???用前景。
