Abstract: A stator-type mixing device is used as a mixing device between fixed catalyst beds in a reactor. The mixing device includes a plurality of blades or surfaces arranged around a central hub. The blades are arranged at an angle relative to vertical so that a fluid cannot pass vertically through the mixing device without contacting at least one blade or surface. The blades or surfaces allow the stator-type mixing device to span the full cross-sectional surface area of the reactor, so that concentration of liquids in a localized portion of the reactor cross-sectional area is reduced or minimized. For reactors where at least part of the process fluid is a liquid under reaction conditions, a distributor tray can be included below the stator-type mixing device.

Abstract: Systems and methods are provided for processing of challenged feedstocks to produce distillate fuel products, such as jet boiling range products and/or diesel boiling range products. The challenged feedstocks can have a high aromatics content, a low API gravity, and/or a low cetane index/cetane number. A feedstock can be processed to form distillate fuel products by processing the feedstock in reaction system including at least two stages. The first stage can perform an initial amount of hydrotreating and/or hydrocracking, while the second stage can include exposing a portion of the hydrotreated and/or hydrocracked effluent to a USY catalyst including a supported noble metal. The USY catalyst can have a desirable combination of catalyst properties. Processing a challenged feedstock in a second stage with the USY catalyst having a desirable combination of properties can allow for production of an increased yield of distillate fuel from the challenged feedstock.
