A study is being made by the National Petroleum Council Committee on Synthetic Fuels from oil shale. The committee has prepared designs and estimates for facilities to produce gasoline and middle distillates using processes developed by the Union Oil Co. of California. This report presents the design of alternative methods for processing oil shale and shale oil. The oil shale retorting method is a recent development which shows considerable promise. The approach to shale-oil refining is basically different in that residual fuels are produced in about the same proportion to distillates as are currently marketed on the Pacific Coast whereas the proposal already evaluated converts shale oil to gasoline, middle distillates, and coke. Residual fuels are and will continue to be an important factor in the petroleum market. Since shale oil, being a heavy crude, is particularly adapted to residual fuel production, a refining plan such as is presented n this report likely will find a place in the future shale-oil industry.
