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.
