Oil shale deposits constitute a large reserve of oil stocks. These immense deposits can potentially be used most conveniently as a source of middle distillate fuels such as jet fuel. The characteristic of the jet fuel distillation cut is a high n-alkane content. Jet fuels require a large n-alkane fraction in order to simultaneously meet both the freezing point and flash point requirements. The conditions reported in this study mimic the refining process known as delayed coking. This study focuses on a method for the rapid determination of the middle distillate fuel potential of shale-derived fuels.
