Abstract: The present invention relates to a method of producing a feedstock for high-quality lube base oil from unconverted oil (UCO) obtained from fuel oil hydrocracking, and more particularly to a method of producing a feedstock for high-quality lube base oil by treating vacuum gas oil (VGO) or a mixture of vacuum gas oil (VGO) with coker gas oil (CGO) or deasphalted oil (NAO) as a feedstock in a hydrotreating unit and a first hydrocracking unit and recycling the resulting unconverted oil (UCO) through a second hydrocracking unit.

A first and second input shaft rotating coaxially with the main input shaft. A first and second clutch, first and third drive gears formed on an input shaft, and second and fourth drive gears formed on the other input shaft.

A second output device for selectively changing torques of the first, second, third, and fourth drive gears and for outputting the changed torque. Also included is a differential gear commonly connected to the first output device and the second output device. The layout provides for only four drive gears on input shafts that enables a total of seven speeds, and a compact double clutch transmission.
