  • Reduced gas holdup in an ebullated bed reactor
    Patent number: 5308476
    Abstract: A resid refining reactor has an ebullated catalyst bed. Hydrogen gas is released into the catalyst bed at a point which is far enough above a distributor plate at the bottom of the catalyst bed to form a gas updraft in a committed zone through the bed. This committed updraft causes a reduction in gas holdup which increases the residence time of a liquid phase in the catalyst bed.

  • Methods of tar sand bitumen recovery
    Patent number: 5143598
    Abstract: Methods for the recovery of bitumen from tar sands comprising the steps of mixing tar sand, solvent and a displacing amount of aqueous medium to form a mixture, followed by separating a bitumen-rich solvent phase from the mixture and recovering bitumen from the bitumen-rich solvent phase are disclosed.

  • Hydroconversion process using mixed catalyst system
    Patent number: 5009771
    Abstract: Disclosed is an improved process for the hydrodemetallization, hydrodesulfurization, hydrodenitrogenation, and hydroconversion of a hydrocarbon feedstock containing asphaltenes, metals and Shell hot filtration solids precursors. The process utilizes a catalyst mixture wherein one component of the mixture is a relatively small pore catalyst and another component is a catalyst that possesses a relatively large amount of macropore volume.

  • Process for reducing resid hydrotreating solids in a fractionator
    Patent number: 4808298
    Abstract: An effective hydrotreating process is provided to minimize precipitation of asphaltenic solids in the product oil. In the preferred process, an aromatic diluent, preferably comprising decanted oil, is injected into one or more of the fractionators downstream of the reactor.

  • Process for the hydrodemetallation hydrodesulfuration and hydrocracking of a hydrocarbon feedstock
    Patent number: 4746419
    Abstract: Disclosed is an improved hydroconversion process for the hydroconversion of heavy hydrocarbon feedstocks containing asphaltenes, metals, and sulfur compounds which process minimizes the production of carbonaceous insoluble solids and catalyst attrition rates. The process is characterized by the use of a catalyst which has about 0.1 to about 0.3 cc/gm of its pore volume in pores having diameters greater than 1,200.ANG. and no more than 0.1 cc/gm of its pore volume in pores having diameters greater than 4,000.ANG..

  • Method for solvent treating of tar sands with water displacement
    Patent number: 4722782
    Abstract: A method for the recovery of bitumen from tar sand comprises slurrying tar sand with about 0.5 to about 4.0 pound of a organic solvent per pound of tar sand, then adding greater than about 0.50 pound water per pound of tar sand, and separating a bitumen rich solvent phase. The method has the advantage of permitting separation of sand from the bitumen rich solvent extract without formation of a stable emulsion.

  • Recovery of a carbonaceous liquid with a low fines content
    Patent number: 4699709
    Abstract: A method for removing solid fines in an extraction of bitumen by (1) extracting bitumen with a mixed solvent comprising at least one solvent with a solubility parameter higher than that of the bitumen and at least one solvent with a solubility parameter lower than that of the bitumen to obtain a bitumen laden solvent mixture and (2) treating the bitumen laden solvent mixture to remove the lower solubility parameter solvent to precipitate undissolved asphaltenic bitumen and solid fines.
