Plural Stage Treatments With Hydrogen Patents (Class 208/210)
  • Patent number: 11084990
    Abstract: Low sulfur gasoline blend stock is produced by a hydrodesulfurization process including at least two hydrodesulfurization reactors with hydrogen feeds and two finishing reactors arranged where the first polishing reactor converts both thiophenic compounds and mercaptans to hydrogen sulfide and hydrocarbons and the second polishing reactor uses a catalyst that has much less thiophenic conversion activity but is operated at a higher temperature to more substantially reduce the sulfur content of the gasoline present in the form of mercaptans. As the conversion of thiophenes to hydrogen sulfide is correlated to reducing octane number, using a second polishing reactor that has little activity for thiophene conversion also protects the high-octane species in the gasoline thereby minimizing octane loss while reducing total sulfur content to acceptable levels. The sulfur left in the gasoline is biased toward higher thiophene content and away from mercaptan content.

  • Publication number: 20140374318
    Abstract: A multi-stage hydrotreating process obtains ultra-low sulfur diesel boiling range hydrocarbon having less than 10 ppm sulfur with elimination of external hot high pressure separator and avoids the formation of recombinant mercaptans by removing excess hydrogen sulfide formed during hydroprocessing reaction. The process includes mixing a diesel boiling range hydrocarbon feedstock with hydrogen and sending to the first predominantly liquid phase hydroprocessing reaction stage. Effluent from the first hydroprocessing reaction stage is sent to first separator zone of open and empty space in the upper part of the second hydroprocessing reaction stage to flash off the dissolved reaction products hydrogen sulfide and ammonia. Liquid part of the effluent of first hydroprocessing reaction stage is passed to the second predominantly liquid phase hydroprocessing reaction stage.

  • Patent number: 8828218
    Abstract: This invention provides methods for multi-stage hydroprocessing treatment of FCC naphthas for improving the overall production quantity of naphtha boiling-range materials during naphtha production for low sulfur gasolines. Of particular benefit of the present processes is the selective treating of cat naphthas to remove gums instead of undercutting the overall naphtha pool by lowering the end cutpoints of the cat naphtha fraction. This maximizes the amount of refinery cat naphtha that can be directed to the gasoline blending pool while eliminating existing processing problems in hydrodesulfurization units. The processes disclosed herein have the additional benefit of minimizing octane losses in the increased naphtha pool volume.

  • Patent number: 8764970
    Abstract: The present invention relates to quenching, during hydroprocessing of a hydrocarbon feed stream. More particularly, the present invention provides for quenching in hydroprocessing of a hydrocarbon feed stream through a hydroprocessing vessel. Liquid quenches (from high pressure hot separator) were installed to assist in cooling the reactor inter-bed, and to maintain good liquid irrigation of the catalyst. The soluble hydrogen in the stream, kinetically active and available for immediate reaction, is the final piece of the puzzle for why this unit runs so well.
