  • Publication number: 20230287280
    Abstract: A process for hydroprocessing a renewable feedstock involves introducing the renewable feedstock and hydrogen in a downward flow into a top portion of a fixed-bed reactor and distributing the downward flow to a top surface of a first catalyst bed in a manner such that the top surface is uniformly wetted across the reactor cross section. The feedstock then flows downwardly through the first catalyst bed, where it is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetallization, hydrocracking, hydroisomerization, and combinations thereof. A hydrocarbon liquid separated from the reaction effluent is recycled to the renewable feedstock in a ratio of 0.4:1 to 1.8:1, based on the volume of the renewable feedstock.

  • Patent number: 10214698
    Abstract: A method providing for the selective hydroprocessing of cracked naphtha feedstock to make a low-sulfur gasoline blending component. The method includes the use of two catalytic distillation stages in combination with two stripping columns and two fixed-bed reactors integrated in a novel arrangement so as to provide for the treatment of cracked naphtha feedstock that has a high sulfur concentration to yield exceptionally low-sulfur light cracked naphtha and heavy cracked naphtha products. The desulfurized light and heavy cracked naphtha are produced with a minimal amount of hydrogenation of the olefin content and at may suitably be used as gasoline blending components.
