  • Patent number: 6444116
    Abstract: An integrated process for treating a vacuum gas oil, kerosene, naphtha and Diesel-containing feed, includes the steps of providing a reaction feed containing residue, vacuum gas oil, kerosene, naphtha, Diesel, hydrogen sulfide, ammonia, and C1-C4 gas phase compounds; providing a stripping gas; providing a washing feed; and feeding the reaction feed, the stripping gas and the washing feed to a stripping and washing zone so as to obtain a gas phase containing the hydrogen sulfide, the ammonia, the C1-C4 gas phase compounds, the naphtha, the kerosene, the Diesel and the vacuum gas oil and a liquid phase, wherein the reaction feed is provided at a reaction feed pressure of between bout 700 psig and about 3500 psig, and wherein the stripping and washing zone is operated at a pressure within about 80 psig of the reaction feed pressure.

  • Patent number: 5558766
    Abstract: A tri-elemental catalyst on a support that includes a pentasil crystalline zeolite and is suitable for hydrocracking and hydrogenation of aromatics-containing petroleum hydrocarbon feedstocks such as hydrotreated cracked feedstock, virgin feedstock, vacuum distillate, middle distillate, mixtures thereof, and the like, is disclosed. The catalyst is suitable for hydrodesulfurization as well as hydrodenitrogenation, thus the feedstock can contain sulfur and nitrogen in addition to the aromatic components. Hydrocracking and aromatics hydrogenation of the petroleum hydrocarbon feedstocks is accomplished under a relatively wide range of process conditions in plural process zones using the tri-elemental catalyst that contains a catalytically active metal phase constituted by a Group VI-B element, a Group VIII first transition series element and a Group VIII second transition series element.
