A novel method of refining oil shale retorting apparatus and

The invention relates to a novel oil shale dry distillation and oil refining method and a novel oil shale dry distillation and oil refining device. Firstly, the invention provides the oil shale dry distillation and oil refining method. In the method, oil shale particles with granularity less than 15mm are used as raw materials; and high temperature flue gas generated by burning semicoke and/or dry distillation gas is utilized to indirectly heat the oil shale particles so as to realize dry distillation of oil shale. The invention also provides the novel oil shale dry distillation and oil refining device for the oil shale dry distillation and oil refining method. Due to the adoption of the oil shale dry distillation and oil refining method and the oil shale dry distillation and oil refiningdevice, which are provided by the invention, high shale oil yield can be obtained, recycling of various products can also be realized, the burning utilization effect of the semicoke is high, and the utilization rate of the oil shale can reach 100 percent. The oil shale dry distillation and oil refining method and the oil shale dry distillation and oil refining device are not only beneficial for improving the economic benefits, but also are beneficial for protecting the environment.
