The overall objective of this project was to demonstrate innovative technology to reduce the cost of converting shale oil to high yields of aviation turbine fuels. To carry out this program, UOP selected a processing scheme involving two stages of hydrotreating followed by hydrocracking. The phase III and IV programs included first stage hydrotreating using the hydrocracking process, naphtha hydrotreating and catalytic reforming, arsenic management studies, an investigation of shale oil fouling, a shale oil/petroleum stability/compatibility study, and an economic analysis of the proposed upgrading scheme.
