Abstract: Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.

Abstract translation: 提供了用于提高瓦斯油原料如真空瓦斯油加氢处理的馏出物产率的方法。 已经意外地发现，在进料的初始加氢处理期间汽提汽提或分馏以分离馏出物馏分可以在所需量的原料转化率下提供馏出物产率的显着增加。 馏出物产物的产率的改善可以在减少或最小化石脑油（或更低）沸点产物的量的同时，在用于产生润滑基础油产品的原料上进行所需水平的转化。 或者，馏出物产物的产率的提高可以对应于在单次通过反应体系期间的提高的产率，使得即使不产生润滑剂沸程产物，馏出物产率也增加。
