    摘要： 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.

    摘要： Disclosed herein is a method of producing feedstock of high-quality lube based oil by producing coker gas oil (CGO) from vacuum residue (VR) or a mixture (VR/AR) of atmospheric residue (AR) and vacuum residue (VR), performing a hydrotreating process and a hydrocracking process by mixing the coker gas oil (CGO) with vacuum gas oil (VGO) to form unconverted oil (UCO), and then recycling the unconverted oil. The method of producing feedstock of high-quality lube based oil is advantageous in that feedstock of high-quality lube based oil can be more economically and efficiently produced using cheap coker gas oil (CGO), which is hard to treat.

    摘要翻译： 本文公开了通过从减压残渣（VR）或大气残留物（AR）和减压渣油（VR）的混合物（VR / AR）生产焦化瓦斯油（CGO）来生产高质量润滑油基油的原料的方法， 通过将焦化瓦斯油（CGO）与减压瓦斯油（VGO）混合以形成未转化的油（UCO），然后再循环未转化的油，进行加氢处理和加氢裂化过程。 生产优质润滑油的原料油的方法的优点在于，使用难以处理的廉价焦化瓦斯油（CGO）可以更经济有效地生产高品质润滑油基油。

    摘要： Disclosed is a process for preparing dimethyl ether, including a) reacting methanol containing 0-80 mol % of water in the presence of a dehydration catalyst, b) transferring the reaction product into a single separation column, thus separating dimethyl ether, water, and unreacted methanol, c) withdrawing dimethyl ether and withdrawing unreacted methanol from the sidestream of the single separation column, and d) recyling the unreacted methanol to the a) reacting the methanol. Dimethyl ether may be prepared from water-containing methanol, and the separation and withdrawal of dimethyl ether, water, and unreacted methanol may be realized using a single column, thus reducing the investment cost and the operating cost.
