Abstract: Technology including relative RN-32V/RHC-3 catalysts for enhancing jet fuel yield and high quality tail oil were applied at the 2.0 Mt/a hydrocracking unit of SINOPEC Yanshan Company for the 2nd production period. The long-term operation and performance test results showed that the improvements in jet fuel yield and hydrocracking tail oil quality were significant: compared with the 1st production period, the jet fuel yield increased 7.11 percentage points and the BMCI value of tail oil was 2 units lower with similar yields. The energy consumption of the unit was gradually reduced annually, average comprehensive energy consumption was 830.98 MJ/t in 2011.
