Research and application of efficient utilization technology of oil shale fractions
Oil shale is a new type of oil Unconventional oil resource with rich reserves.Most of the mature oil shale retorting technologies treat massive shale with oil content of 12~75 mm and above 3.5%,and the oil recovery rate is low.In order to improve the utilization ratio of resources and ensure the efficient utilization of resources,the technology of high efficient utilization of oil shale has been studied.The results show that:through the combination of three kinds of retorting technologies:the homogeneous fractionation of massive shale,the fork-flow retorting of small-size shale,and the coupling retorting of low-grade shale and organic solid waste,the utility model can realize the high efficient utilization of the oil shale with full grain size and full grade.
