国内某炼厂0.8 Mt/a加氢裂化装置由于所产柴油产品产率偏低、密度偏低，导致全厂仅能生产调和硫含量低于350μg/g的国Ⅲ标准车用柴油产品。根据柴油国V质量升级的需要以及目前装置运行过程中存在的问题，对该装置进行技术改造，催化剂更换为抚顺石油化工研究院开发的FF-46加氢精制、FDW-3临氢降凝和FC-14B加氢改质催化剂组合，采用加氢改质（降凝）操作模式，由一段串联全循环工艺流程改为一段串联一次通过工艺流程，装置改造后可以生产硫含量低于10μg/g 的国 V 标准车用柴油产品，柴油产品密度由800~805 kg/m3提高至812~810.4 kg/m3，柴油产品产率由50.46%提高至88.90%~97.20%。同时考虑到装置原料变差的可能性，通过切换操作，工艺流程可以由一段串联一次通过工艺流程恢复至一段串联全循环工艺流程，给原料加工和生产操作带来极大的适应性。

The density and yield of the diesel produced in a domestic 0.8Mt/a hydrocracking unit are low, which causes that the refinery can only blend China III diesel with sulfur content of less than 350μg/g. Technical revamp of the unit is needed to meet China V diesel production and resolve current problems during operation. The unit operation mode is turned to the hydroupgrading with FRIPP catalyst of FF-46, FDW-3 and FC-14B. The unit process flow is turned to a series of once through process from a series of full circulation. The revamped unit can produce China V diesel with sulfur content of less than 10μg/g, whose density is improved to 812~810.4 kg/m3 from 800~805 kg/m3, and yield is improved to 88.90%~97.20%from 50.46%. Considering the possibility of raw material variation, the process flow can recover to a series of full circulation from a series of once through process, which brings great adaptability for raw materials processing and production operation.
