Summary:PURPOSE: Provided is a process for producing both fuel and lubricating oil from a single integrated hydrocracking system, by which it is possible to produce a high yield and high quality fuel as well as lubricant stream having and a wide viscosity range and a wide viscosity index range. CONSTITUTION: A liquid hydrocarbon feedstock is contacted with hydrogen over a first catalyst in a hydroprocessing zone to yield a first effluent containing a normal liquid fraction. The hydroprocessing zone is operated at either hydrotreating or hydrocracking conditions and also is operated at conditions effective to remove impurities contained in the feedstock. The normally liquid fraction is separated from the first effluent by boiling point range to yield at least a first lubricating oil product, a first fuel product and a bottom fraction. At least a portion of the bottom fraction is contacted with a second catalyst in a hydrocracking zone operated at conditions effective to hydrocrack the bottom fraction to yield a second effluent. The second effluent is separated according to the boiling point range to yield an overhead stream and a recycle stream. The recycle stream is recycled to the hydrocracking zone. 복합 증류 하이드로크래킹 방법은 일차 반응 단계로부터 하나이상의 연료 생성물 및 하나이상의 윤활 생성물을 생성시킨다. 윤활 생성물로 회수되지 않은 일차 단계로부터의 중(heavy) 분율은 이차 반응 단계에서 연료로 분해된다. 본 발명은 연료 하이드로크래커로부터 넒은 점도 범위 및 넓은 점도지수 범위에 걸친 전체 범위의 윤활 스트림 뿐만 아니라 고수율의 고품질 연료를 제공하고자 한다.
