Abstract: To increase jet fuel and reduce diesel production was the key to refinery to adapt to changes in domestic oil market by adjusting product structure and improving product quality and operation efficiency. Increasing the kerosene yield of CDU and hydrocracker was the main way to increase the production of jet fuel. However, the jet fuel production was limited by the yield of No.1 side-line of atmospheric distillation tower and hydrocracking products solutions. This paper analyzed the current bottlenecks in jet fuel production of refineries, described the technologies for maximum production of jet fuel from conventional hydrocracking and SR diesel hydrcracking. Meanwhile, the technology application effect was summarized. Based on the above analysis, some suggestions were suggested.

Key words: jet fuel, diesel, CDU, hydrocracking
