Abstract: The new generation hydrocracking catalyst RHC-133 was developed by SINOPEC Research Institute of Petroleum Processing Co., Ltd. Compared with the third generation hydrocracking catalyst, the catalyst has higher selectivity of jet fuel and better quality of tail oil. The commercial application of RHC-133 catalyst in SINOPEC Qilu Company showed that the jet fuel yield of high pressure hydrocracking unit increased by 3.75 percentage points compared with the previous cycle, the diesel cetane index reached 58.9, and the pour point was -47 ℃. The tail oil BMCI decreased by 2.0 to 9.7 compared with the previous cycle. It was a high-quality feedstock for steam cracking to produce ethylene. The unit has achieved significant economic and social benefits. The application of RHC-133 catalyst in a refinery of PetroChina has also achieved similar good results.
