Abstract: Systems and methods are provided for producing upgraded raffinate and extract products from lubricant boiling range feeds and/or other feeds having a boiling range of 400° F. (204° C.) to 1500° F. (816° C.) or more. The upgraded raffinate and/or extract products can have a reduced or minimized concentration of sulfur, nitrogen, metals, or a combination thereof. The reduced or minimized concentration of sulfur, nitrogen, and/or metals can be achieved by hydrotreating a suitable feed under hydrotreatment conditions corresponding to relatively low levels of feed conversion. Optionally, the feed can also dewaxed, such as by catalytic dewaxing or by solvent dewaxing. Because excessive aromatic saturation is not desired, the pressure for hydrotreatment (and optional dewaxing) can be 500 psig (˜3.4 MPa) to 1200 psig (˜8.2 MPa).

Abstract: A process for producing high yields of higher quality (API Group II, Group III′) lubricating oil basestock fractions which allows the production of two or more types of high quality lubes in continuous mode (no blocked operation mode) without transition times and feed or intermediate product tankage segregation. Two consecutive hydroprocessing steps are used: the first step processes a wide cut feed at a severity needed to match heavy oil lube properties. The second step hydroprocesses a light oil after fractionation of the liquid product from the first step at a severity higher than for the heavy oil fraction. The two hydroprocessing steps will normally be carried out in separate reactors but they may be combined in a single reactor which allows for the two fractions to be processed with different degrees of severity.
Abstract translation: 生产高产量的高质量（API Group II，Group III'）润滑油基础油馏分的方法，其允许以连续模式（无阻塞操作模式）生产两种或更多种类型的高质量润滑剂，而不需要过渡时间和进料或 中间产品油罐分离。 使用两个连续的加氢处理步骤：第一步按照重油润滑油性能所需的严重程度处理宽切削进料。 第二步骤是以比重油馏分高的浓度从第一步骤中分离液体产物之后加氢轻质油。 两个加氢处理步骤通常在单独的反应器中进行，但是它们可以在单个反应器中组合，这允许以不同的严重程度处理两个馏分。
