Processing of heavy hydrocarbon feeds
Abstract
Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.
Claims
exact text as granted — not AI-modified1 .- 15 . (canceled)
16 . A process for producing a hydroprocessed product, comprising:
exposing a combined feedstock comprising a heavy oil feed component and at least about 5 wt % of a High Solvency Dispersive Power (HSDP) crude component to a hydroprocessing catalyst under effective fixed bed hydroprocessing conditions to form a hydroprocessed effluent, the effective fixed bed hydroprocessing conditions including a pressure of about 1500 psig (˜10.3 MPa) or less, a temperature of at least about 360° C., and a liquid hourly space velocity of the fraction of the combined feedstock boiling above 1050° F. (˜566° C.) of at least about 0.10 hr −1 , the HSDP crude component having a TAN of at least about 0.3 and a solubility blending number of at least about 75, the HSDP crude component optionally comprising an aromatics content of at least about 50 wt %.
17 . The process of claim 16 , wherein the HSDP crude component has a 10% distillation point of at least about 800° F. (˜427° C.).
18 . The process of claim 16 , wherein the heavy oil feed component has a 10% distillation point of at least about 900° F. (˜482° C.).
19 . The process of claim 16 , wherein the effective fixed bed hydroprocessing conditions are effective for conversion of from about 50 wt % to about 70 wt % of the ˜1050° F.+(˜566° C.+) portion of the heavy oil feed component.
20 . The process of claim 16 , further comprising exposing the combined feedstock to a demetallization catalyst under hydrodemetallation conditions prior to exposing the combined feedstock to the hydroprocessing catalyst, the demetallization catalyst comprises about 5 wt % to about 60 wt % of a regenerated catalyst extruded with a support, the demetallization catalyst having a pore volume of at least about 0.5 cm 3 /g, the regenerated catalyst comprising 1.0 wt % to 30 wt %, relative to the weight of regenerated catalyst, of a Group 6 metal, a Group 8-10 metal, or a combination thereof.Join the waitlist — get patent alerts
