Abstract: Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.
Abstract translation: 提供了用于处理衍生自热裂化残渣馏分的脱沥青瓦斯油以形成组I，组II和/或组III润滑剂基础油的方法。 相对于常规方法，润滑剂基础油（任选地也称为基础油料）的产率可以通过以单程严重程度的中间水平热裂解渣油馏分来提高。 通过对部分转化水平进行热裂解，可以保留残渣部分中有利于提高润滑剂基础油的粘度和粘度指数的化合物，从而可以提高较高粘度的润滑剂基础油的产率， 热裂解渣油馏分。
