  • Patent number: 10385277
    Abstract: Disclosed herein is a catalyst for producing biodiesel, including a carrier having water resistance and an active component supported on the carrier and used in a hydrotreating reaction or a decarboxylation reaction. Since the catalyst for producing biodiesel includes a carrier having strong water resistance, the deactivation of the catalyst due to the water produced through a process of producing HBD can be prevented, thus remarkably improving the long term stability of a catalyst.
    Type: Grant
    Filed: June 30, 2016
    Date of Patent: August 20, 2019
    Assignees: SK INNOVATION CO., LTD., SK ENERGY CO., LTD.

  • Publication number: 20140150332
    Abstract: Disclosed is a catalyst including metal phosphide for preparation of biodiesel, and a method of preparing biodiesel from feedstock comprising vegetable oil through hydrotreating using the catalyst. When the catalyst including metal phosphide is used as a catalyst for preparation of biodiesel, preparation activity of hydrotreated biodiesel is high even without continuous supply of sulfiding agent, and hydrotreating and isomerization reactions occur at the same time, thus obtaining high-quality hydrotreated biodiesel having a low pour point.
