  • High activity and high distillate yield hydrocracking catalysts with intimate interaction between unsupported metal oxide and zeolite
    Patent number: 11826738
    Abstract: A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.
    Type: Grant
    Filed: July 20, 2021
    Date of Patent: November 28, 2023
    Assignee: UOP LLC

  • PROCESSES AND APPARATUSES FOR OXIDIZING ELEMENTAL MERCURY IN FLUE GAS USING OXYCHLORINATION CATALYSTS
    Publication number: 20130004395
    Abstract: Processes for decreasing elemental mercury in flue gas stream are provided. The processes include receiving the flue gas stream containing elemental mercury in an oxidation zone and maintaining the oxidation zone at a temperature of less than about 200° C. In the oxidation zone, the flue gas stream is contacted with an oxychlorination catalyst. As a result, the elemental mercury is oxidized to create oxidized mercury in an oxidized flue gas. The oxidized mercury is then removed from the oxidized flue gas.

  • PROCESSES AND APPARATUSES FOR ELIMINATING ELEMENTAL MERCURY FROM FLUE GAS USING DEACON REACTION CATALYSTS AT LOW TEMPERATURES
    Publication number: 20130004396
    Abstract: Processes for decreasing elemental mercury in flue gas stream are provided. The processes include receiving the flue gas stream containing elemental mercury in an oxidation zone and maintaining the oxidation zone at a temperature of less than about 200° C. In the oxidation zone, the flue gas stream is contacted with a Deacon reaction catalyst. As a result, the elemental mercury is oxidized to create oxidized mercury in an oxidized flue gas. The oxidized mercury is then removed from the oxidized flue gas.
