    摘要: A process is provided for producing a heavy lubricating base oil by hydrocracking a lubricating oil feedstock at high yield. The lubricating oil feedstock contains a hydroprocessed stream that is difficult to process using a conventional catalyst system. The catalyst used in the process includes a mixed metal sulfide catalyst that comprises at least one Group VIB metal and at least one Group VIII metal. The process also provides for hydroisomerization and hydrofinishing process steps to prepare the lubricating base oil.
