Forecasts of heavier, higher sulfur crudes show the need for more hydrotreat-ing for sulfur removal. Increasing demands for middle distillate products will require more conversion of heavy fractions and more hydrogen processing. JP-5 jet fuel, normally a straight run product, is likely to be made by hydrogenation and hydrocracking with resulting changes in properties. Synthetic crudes from oil shale and coal have special processing needs and will introduce other changes in chemical and physical properties. The study identified properties of future JP-5 production for use in an alternate test procedure to qualify new Navy jet fuels.
