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.

Reduced gas holdup in an ebullated bed reactor

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.

Methods of tar sand bitumen recovery

A hydrotreating process if provided in which resid and resins are hydrotreated with hydrogen-rich gases in the presence of a hydrotreating catalyst in an ebullated bed reactor.

Resid hydrotreating with resins

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.

Hydroconversion process using mixed catalyst system

A process is provided in which solvent-extracted oil or other deasphalted oil derived from hydrotreated resid is catalytically cracked to increase the yield of gasoline and other high value products.

Catalytic cracking with deasphalted oil

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 reducing resid hydrotreating solids in a fractionator

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..

Process for the hydrodemetallation hydrodesulfuration and hydrocracking

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.

Method for solvent treating of tar sands with water displacement

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.

Recovery of a carbonaceous liquid with a low fines content

A method is disclosed for recovering bitumen from a carbonaceous solid feed and for recovering a carbonaceous liquid from a fines-containing carbonaceous liquid feed by extraction of the feed with a solvent of predetermined solvency power, wherein the recovered product has a low fines content.
