Current Status and Energy Analysis of Oil Shale’s Retorting Process in the World

The application progress of oil shale retorting process at home and abroad is mainly introduced, and the advantages and disadvantages of dry distillation furnaces in different countries are compared. The development trend of oil shale retorting process is prospected. At present, several oil shale retorting technologies have been applied and newly appeared in Fushun furnace retorting, fluidized bed retorting and decarbonization processes, convection heating oil shale mining processes, ATP dry distillation furnaces, ICP retorting furnaces, etc. Very mature, but the oil recovery rate using these technologies is relatively low. The industrialized dry distillation technology currently being put into production at home and abroad has been discussed, and the problems in the dry distillation technology have been studied.
