Abstract: Methods are provided for hydroprocessing a feed (such as hydrotreating, hydrocracking, or hydrofining a feed) to generate a product with a reduced or minimized aromatics content relative to the severity of the hydroprocessing conditions. In some types of hydroprocessing applications, it can be desirable to select the severity of hydroprocessing conditions to achieve a desired level of removal for sulfur, a desired level for removal of nitrogen, and/or a desired level for increasing the viscosity index of a feed. The severity for heteroatom removal and/or viscosity index uplift can also correspond to an amount of conversion of a feed to lower boiling point products, so the lowest severity conditions suitable for achieving a product quality can be desirable. By improving the aromatics saturation during hydroprocessing, the severity of subsequent aromatics saturation processes can be reduced.
Abstract translation: 提供用于加氢处理饲料（例如加氢处理，加氢裂化或加氢精制饲料）以产生相对于加氢处理条件的严重性降低或最小化芳烃含量的产物。 在一些类型的加氢处理应用中，可以期望选择加氢处理条件的严重性以达到期望的硫去除水平，除去氮的所需水平和/或用于提高进料粘度指数的期望水平 。 杂原子除去和/或粘度指数升高的严重程度也可以对应于进料到低沸点产物的转化量，因此适合于获得产品质量的最低苛刻度条件是可取的。 通过改善加氢处理过程中的芳族化合物饱和度，可以降低随后的芳烃饱和过程的严重性。
