Development and Application of Hydrocracking Technology for Increasing Jet Fuel and High Quality Tail Oil in Large Proportion
In order tomeet the shortage of jet fuel and the transformation of refining unit,a new generation of hydrocracking catalyst RHC-131 and hydrocracking refining section catalyst RN-410 have been introduced.Based on the new catalyst and systematic process research,the hydrocracking technology has been successfully developed to increase the production of jet fuel in a large proportion and also to produce high-quality tail oil.The results of the application of the high-pressure hydrocracking unit of some company with a capacity of 2 million tons/year show that the technology can substantially increase the jet fuel yield and reduce the BMCI value of the tail oil,and also produce more diesel oil through the change of the distillation cut to adapt to the change of the market demand.The successful implementation of this technology has enabled the high-pressure hydrocracking unit to realize multiple benefits such as quality improvement,efficiency increase,carbon reduction and cost reduction.
