摘　　要：哈尔滨石化分公司利用原中压加氢改质装置的工艺流程,与抚顺石化研究院合作开发了加氢精制/临氢降凝组合工艺。通过用大庆催化裂化重柴油、轻柴油和常三线蜡油按不同配比进行试验,发现以催化裂化轻柴油为原料生产-35#低凝柴油组分,具有反应条件缓和、柴油收率高、催化剂再生周期长的优点。Based on the original medium pressure hydrofining plant process flow, the hydrofining/hydrodefreezing combined process is developed with the collaborating of Fushun Petrochemical Research Institute. By testing with different mixing ratio of Daqing FCC heavy diesel oil, light diesel oil and crude unit third line oil, it is concluded that producing No35 low freezing point diesel can be realized from FCC light diesel oil as raw material, and it has advantages of mild reaction conditions, high diesel yield, long catalyst regeneration period.
