  • Patent number: 11072748
    Abstract: Improved catalytic reforming processes and systems employ reforming reactors in a more efficient manner and can avoid problems associated with yield loss. Aromatics and isoparaffins are separated prior to passing to a reforming unit. An integrated process for producing gasoline blending components includes: separating a naphtha feedstream into an aromatic-rich stream and an aromatic-lean stream; separating the aromatic-lean stream into an isoparaffin-rich stream and an isoparaffin-lean stream; and catalytically reforming the isoparaffin-lean stream to produce a reformate stream.
    Type: Grant

  • Patent number: 10596555
    Abstract: This invention relates to a hydrodesulfurization catalyst, a method for preparing the catalyst, and a method for the preparation of low sulfur gasoline fuel with minimal loss of RON. The catalyst particles include a group VIB metal and a support material having relatively high surface area, and optionally includes one or more group VIIIB metal. The method for preparing the catalyst allows for greater loading of the active metal species on the surface of the support material under aqueous reaction conditions.

  • Patent number: 8366913
    Abstract: The invention relates to a process for the desulfurization of a gasoline fraction with high recovery of olefins and reduced loss of Research Octane Number (RON). A petroleum fraction is contacted with hydrogen and a commercially available hydrodesulfurization catalyst under mild conditions with to remove a first portion of the sulfur present, and is then contacted with an adsorbent for the removal of additional sulfur.

  • Patent number: 8216520
    Abstract: A process for upgrading heavy oil by mixing the heavy oil with water fluid using an ultrasonic wave generator prior to increasing the temperature and pressure of the mixture to values near to or exceeding the critical point of water, to produce low pour point, high value oil having low sulfur, low nitrogen, and low metallic impurities for use as hydrocarbon feedstock.
