  • Patent number: 10920636
    Abstract: Systems and methods are provided for performing selective catalytic reduction on engine exhaust using ethanol from the engine fuel as the reducing agent. Fuel from a fuel tank or other fuel source can be passed through a separation module to produce a fuel stream with a reduced ethanol content and an ethanol-enriched fraction. After combustion of fuel under lean conditions, the combustion exhaust can be exposed to a catalyst system in the presence of the ethanol-enriched fraction.

  • Patent number: 10900423
    Abstract: Systems and methods are provided for performing on-board separation of a fuel into a higher octane fuel fraction and a lower octane fuel fraction using a membrane under osmosis conditions. By performing the separation under osmosis conditions, the feed for separation can be exposed to the membrane without requiring prior heating. This can avoid the need for having a separate heat exchanger system for heating the feed to the membrane to a desired temperature range. Additionally or alternately, the permeate from the membrane separation can be at a pressure of roughly 100 kPa-a or higher. This can avoid the need for having an eductor to provide a pressure below 100 kPa-a for the permeate side of the membrane. The fuel fractions produced during the membrane separation can then be used as fuel in a dual-fuel spark ignition engine.

  • Publication number: 20200325406
    Abstract: A molecular separation method can include: passing a deasphalted oil stream through a reactor containing an active substrate, wherein the catalytic active substrate adsorbs heteroatom species from the deasphalted oil stream and produces a pretreated hydrocarbon feed stream essentially free of 4+ ring aromatic molecules (ARC 4+ species), metal species, and heteroatom species; and chromatographically separating with a simulated moving bed apparatus or a true moving bed apparatus (SMB/TMB) the pretreated hydrocarbon feed stream into a saturate fraction and an aromatics fraction.
