Using the background and product characteristics of coal aneoil shale liquefaction processes, estimates were made of the type of refining needed to increase presentday specification jet fuel availability. It was found that shale oil, which is chemically similar to petroleum, can contribute directly to fuel availability by being fully integrated into conventional petroleum refinery feed streams. Thus, in about a decade, a fraction of the commercial jet fuel will proably come from shale oil. This shale oil will be transported by pipeline from the mine/retort site to the refinery with a minimum amount of hydroprocessing. Coal, on the other hand, is not expected to be integrated into the jet fuel refining process because of its very high concentration of aromatic and napthenic compounds. Rather, it will be used selectively to free virgin petroleum stocks for paraffinic-based fuels production. Coal liquids are expected to be used for gasoline production in order to reduce reforming requirements. Some hydroprocessed coal liquids might be used in jet fuel manufacturing to increase the supply by increasing the levels of naphthenes and aromatics.
