Catalytic Patents (Class 208/108)
  • Patent number: 11118119
    Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to produce less fouling sediment. The dual catalyst system more effectively converts sediment-forming precursors to produce sediment that is less fouling than sediment produced using only the heterogeneous catalyst and not the dispersed metal sulfide particles. The dual catalyst system provides for a lower rate of equipment fouling for a given sediment production rate and/or concentration. In some cases, sediment production rate and/or concentration can be maintained or increased while equipment fouling is reduced. In some cases, sediment production rate and/or concentration can be increased without increasing equipment fouling.

The VCC unit replaces one or more processing steps normally included in refineries as separate and distinct processing units including heavy distillate/gas oil cracking and optionally bottoms upgrading and deep desulfurization of diesel and gasoline range cuts. The refinery design is especially suited for heavy crude upgrading and can be tuned to provide a wide range of gasoline to distillate production ratios.

    Abstract: A method for performing a field operation within a geologic basin having rock formations and a reservoir that includes fluids includes generating, by forward modeling using a petroleum system model (PSM), an estimate of a fluid property distribution of a fluid within the reservoir of the geologic basin. The method further includes detecting, from fluid samples, a fluid property gradient within the geologic basin. The fluid samples are extracted from within at least one wellbore drilled through the rock formations. The method further includes, comparing the estimate of the fluid property distribution with the detected fluid property gradient to generate a comparison result, iteratively adjusting, based on the comparison result, the PSM to generate an adjusted PSM, and performing, based on the adjusted PSM, the field operation within the geologic basin.

  • Patent number: 10041004
    Abstract: A process for de-ashing pitch. The pitch from a slurry hydrocracking process is mixed with a solvent. The mixture is separated into solvent and soluble materials and insoluble materials. The insoluble materials can be dried to recover solvent which may be recycled. The solvent and soluble materials are separated. The solvent may be recovered and recycled. Hi-Sol 15 may be the solvent. Additionally, CSO may be the solvent and a portion thereof may be used with the de-ashed pitch to make an asphalt binder.

  • Patent number: 9783742
    Abstract: A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60° C. to about 200° C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260° C. to about 400° C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes.
