    Abstract: Methods are provided for hydrotreating a feed to generate a product with a reduced or minimized aromatics content and/or an increased distillate product yield. A distillate boiling range feed having an elevated content of sulfur and/or nitrogen can be hydrotreated using at least two hydrotreating stages with intermediate separation to produce a hydrotreated distillate boiling range product with a reduced or minimized aromatics content. Additionally or alternately, a mixed metal catalyst formed from a suitable precursor can be used during the hydrotreating. A mixed metal catalyst formed from a suitable precursor can provide an unexpectedly superior activity for aromatic saturation. A still further unexpected benefit can be achieved by combining a multi-stage hydrotreating process with intermediate separation with hydrotreating in the presence of a mixed metal catalyst formed from a suitable precursor.

    Abstract translation: 提供用于加氢处理进料以产生具有降低的或最小化的芳烃含量和/或增加的馏出物产物产率的产物的方法。 具有提高的硫和/或氮含量的馏出物沸程进料可以使用至少两个具有中间分离的加氢处理阶段进行加氢处理,以产生具有降低的或最小化的芳烃含量的加氢处理的馏出物沸点产物。 另外或者替代地,在加氢处理期间可以使用由合适的前体形成的混合金属催化剂。 由合适的前体形成的混合金属催化剂可以提供出乎意料的优异的芳族饱和活性。 在由合适的前体形成的混合金属催化剂的存在下,通过将多级加氢处理方法与中间分离与加氢处理组合可以实现另外的意想不到的益处。

    Abstract: An in situ process for conducting regeneration of spent hydrocarbon synthesis catalyst. Regenerated, but not yet re-activated, catalyst (15) may be introduced into an operating HCS reactor (1) that has catalyst rejuvenation means (14). Any combination of a fresh, activated catalyst, a fresh, passivated catalyst or short-term or long-term deactivated catalysts may already be present in the HCS reactor (1). The regenerated, but not yet re-activated catalyst is activated in the HCS reactor (1) with rejuvenation means (14) at normal process conditions. The HCS reactor (1) receives syngas through the inlet line (3) and releases liquid hydrocarbons through outlet line (4) and gaseous hydrocarbon and unreacted syngas through the offgas line (2). Catalyst is removed from the HCS reactor (1) through the slipstream line (5) and into a filtration unit (6) which is fed with a stripping fluid (7). The filtered catalyst proceeds to the regeneration unit (9) which is fed a regenerative fluid (10). The regenerated catalyst is returned to the HCS Reactor (1) through the catalyst return line (11) where it is reactivated.
