Abstract: The truly sulfurized (e-Trust)hydrocracking catalysts RHC-131B-TS, RHC-133B-TS for maximizing jet fuel and heavy naphtha and their grading scheme,developed by the SINOPEC Research Institute of Petroleum Processing,was applied commercially in the hydrocracking unit of PetroChina Harbin Petrochemical Company. The unit mainly produces jet fuel distillates, and also produces naphtha and diesel distillates. The application results showed that the time of start-up was shortened about 2 days by using the true sulfurized catalyst, no waste water or exhaust gas were discharged in the process of start-up, the yield of distillate (heavy naphtha + jet fuel) was 71.5%, the smoke point of jet fuel fraction was 35 mm, and the cetane number of diesel fraction was 76. During the long-term operation of the unit, the activity of the true sulfurized catalyst was stable, the product quality was excellent and the product distribution could meet the production demand.
