Abstract: 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.
Abstract translation: 提供一种通过以高产率加氢裂化润滑油原料来生产重质润滑基础油的方法。 润滑油原料含有使用常规催化剂体系难以加工的加氢处理流。 用于该方法的催化剂包括含有至少一种VIB族金属和至少一种第Ⅷ族金属的混合金属硫化物催化剂。 该方法还提供加氢异构化和加氢处理步骤以制备润滑基础油。
