    • A process for producing a product slate, which includes at least three base oil grades having kinematic viscosities at 100° C. within the range between about 1.8 cSt and 30 cSt, from a waxy feed having an initial boiling point of about 340° C. or less and a final boiling point of about 560° C. or higher, said process comprising (a) isomerizing at least a portion of the waxy feed, whereby the amount of isoparaffins present are increased; (b) distilling a first portion of the isomerized waxy feed in light block mode operation into at least three base oil fractions having different boiling ranges; (c) distilling a second portion of the isomerized waxy feed in medium block mode operation into at least three base oil fractions having different boiling ranges; and (d) blending at least one base oil fraction produced from light block mode with at least one base oil fraction produced from medium block mode to produce a lubricating base oil blend meeting a target value for at least one pre-selected property.
    • 一种生产产品板的方法,其包括至少三种在起始沸点为约340℃的蜡质进料中在100℃下的运动粘度在约1.8cSt和30cSt之间的运动粘度的基础油级。 或更低,最终沸点为约560℃或更高,所述方法包括(a)使蜡质进料的至少一部分异构化,由此存在的异链烷烃的量增加; (b)以轻质模式操作将异构化蜡质进料的第一部分蒸馏成具有不同沸程的至少三种基础油馏分; (c)将中间块模式操作中的异构化蜡质进料的第二部分蒸馏成具有不同沸程的至少三种基础油馏分; 和(d)将由轻块模式产生的至少一种基础油馏分与由中等块模式产生的至少一种基础油馏分混合以产生满足至少一种预先选择的性能的目标值的润滑基础油混合物。
