Abstract: To increase jet fuel production and improve refinery benefit, the WEPEC broadened its hydrocracker feedstocks by processing LCO, CDU 2nd and 3rd cuts. Meantime, operation conditions are optimized according to the feed properties to maximize jet fuel. As the raw material range widening, the unit load and the output of jet fuel is improved significantly. After optimization, the jet fuel yield increases by 4.3%, 5.8% and 0.94% using the blending feed with LCO, CDU 1st and 2nd cut, respectively, compared with design requirement. The practice suggests that increase of jet fuel production can increase the benefit of the hydrocracking unit in the current market situation.

Key words: hydrocracking, gas oil, light cycle oil, jet fuel
