In a previous study the development of a single catalyst system was reported which had the unique ability to sequentially saturate, denitrogenate and hydrocrack a whole shale oil into high yields of jet fuel on a once through basis. Examination of the kinetics suggested that improvements in the process and in catalyst activity could be achieved by using a dual catalyst system. The dual catalyst system would consist of the previously developed catalyst and a pretreat catalyst specifically designed to remove nitrogen as ammonia from organo-nitrogen compounds. The increased effectiveness of the dual catalyst system was monitored in two six month catalyst deactivation studies using fully automated, high pressure, fixed bed, minipilot plants. The results indicated that use of a dual catalyst system gave significant improvements in catalyst lifetime and unit throug hput as compared to the single catalyst system. Dual catalyst system lifetimes were projected at approximately 2.0 years for production of 76 wt JP-4 fuel material from whole crude shale oil.
