    • The invention includes a process of making a lubricating composition including: contacting a heavy mineral oil feed in a hydrocracking zone with a hydrocracking catalyst at hydrocracking conditions, whereby at least a portion of the heavy mineral oil feed is cracked; recovering at least one gasoline-range fraction and one bottoms fraction from the hydrocracking zone; passing a first portion of the bottoms fraction including not more than about 67 wt. % of the bottoms fraction to a dewaxing zone; and passing a second portion of the bottoms fraction including at least about 33 wt. % of the bottoms fraction back to the fuels hydrocracker for additional processing; and where the bottoms fraction has a viscosity at 100° C. of less than about 4.0; contacting the first portion of the bottoms fraction with a dewaxing catalyst under catalytic dewaxing conditions, where at least a portion thereof is substantially dewaxed; contacting at least a portion of the substantially dewaxed bottoms fraction with a hydrofinishing catalyst under hydrofinishing conditions, thereby producing a hydrofinished, dewaxed bottoms fraction; and removing from the hydrofinished, dewaxed bottoms fraction at least one light fraction including diesel or jet fuel range material, thereby leaving a heavy fraction including the lubricating composition having a naphthenes content of at least about 33 wt. %.
    • 本发明包括制备润滑组合物的方法,其包括:在加氢裂化条件下使加氢裂化区中的重矿物油进料与加氢裂化催化剂接触,由此至少部分重矿物油进料裂化; 从加氢裂化区回收至少一个汽油范围馏分和一个塔底馏分; 使底部馏分的第一部分通过不超过约67重量% 底部馏分的%至脱蜡区; 并使第二部分底部馏分包含至少约33wt。 %的塔底馏分回到燃料加氢裂化器进行额外处理; 并且其中底部馏分在100℃下的粘度小于约4.0; 在催化脱蜡条件下使塔底馏分的第一部分与脱蜡催化剂接触,其中至少一部分基本脱蜡; 在加氢精制条件下使基本上脱蜡的塔底馏分的至少一部分与加氢精制催化剂接触,由此生产加氢完成的脱蜡塔底馏分; 并且从所述加氢完成的脱蜡塔底馏分中除去包含柴油或喷气燃料范围材料的至少一种轻馏分,从而留下包含润滑组合物的重馏分,所述重馏分具有至少约33重量%的环烷烃含量。 %。

    • An improved catalytic slurry hydroprocess comprising a hydrogenation zone having a hydrogen partial pressure of at least about 100 psia characterized by active catalyst recycle accompanied by minimal catalyst deactivation from coking or asphaltene agglomeration in which the improvement comprises the steps of:(1) separating at least a portion of active catalyst from the liquid hydrogenation product eluted from the hydrogenation zone of said hydroprocess, and(2) recycling at least a portion of said separated active catalyst to said hydrogenation zone;wherein said steps are carried out while maintaining said active catalyst under conditions substantially the same as those encountered in said hydrogenation zone.
    • 一种改进的催化浆料加氢方法,其包括氢分压为至少约100psia的氢化区,其特征在于活性催化剂循环,伴随着焦化或沥青质聚集的最小催化剂失活,其中改进包括以下步骤:(1)至少分离 从所述加氢处理的氢化区洗脱的来自液体氢化产物的一部分活性催化剂,和(2)将至少一部分所述分离的活性催化剂再循环到所述氢化区; 其中所述步骤在将所述活性催化剂保持在与所述氢化区中遇到的条件基本相同的条件下进行。
