Abstract: UOP's UnicrackingTM technology has been licensed for the 4.0 MM TPY VGO hydrocracking unit (including C5 normal isomer separation unit) of Zhejiang Petroleum & Chemical Co., Ltd., which loads hydrotreating catalysts HYT-6219-1.3T/HYT-6219-1.3Q and hydrocracking catalyst HC-185LT.It is the largest single-stage series once-through process flow unit in China.The unit has been operating stably at over 95% of its design capacity after the start-up. The yield of heavy naphtha is 27.67%, the aromatic potential content is 58.3%,the yield of jet fuel is 23.74%, the catalyst has good activity and selectivity at low reaction temperature, the single pass conversion is 83.35%, the C+5 yield is 94.42%, and the comprehensive energy consumption is 1,652.41 MJ/t.The product distribution is reasonable, and the quality meets the design requirements.
