Abstract: A slurry hydroprocessing process for upgrading a hydrocarbon feedstock containing nitrogen and sulfur using bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals wherein the ratio of Group VIB metal to Group VIII metal is about 10:1 to about 1:10.

Abstract: The invention relates to processes for treating acidic crudes or fractions thereof to reduce or eliminate their acidity and corrosivity by addition of suitable amounts of Group IA or Group IIA oxides, hydroxides and hydrates and Group IIA metal naphthenate salts. The process has the additional benefits of reducing materials handling problems associated with treating acidic crude oils using liquid solvents and in reducing emulsion formation.

Abstract: The invention described herein is directed to (a) slurry hydroprocessing (SHP) of a feed under SHP conditions; (b) deasphalting, under deasphalting conditions the product obtained from said step (a) and recovering a solvent deasphalted oil and solvent deasphalted rock; (c) calcining said solvent deasphalted rock at a temperature of ≦about 1200° F. to produce an ash catalyst precursor; (d) recycling said ash catalyst precursor to said step (a).

Abstract: A slurry hydroprocessing process (SHP) where a hydrocarbon feedstock is treated at slurry hydrotreating conditions, in the presence of a hydrogen containing treat gas and in the presence of a supported metallic catalyst which is a supported sulfide of a metal selected from the group of non-noble Group VIII metals, Group VIB metals and mixtures thereof where the support is an inorganic oxide and where the catalyst has an average diameter of about 0.5 to about 100 microns to obtain a first product stream comprising the catalyst and a hydroprocessed feedstream; separating the first product into a catalyst-free product stream and a catalyst-containing stream and recycling at least a portion of the catalyst-containing stream back to the hydroprocessing step.

Abstract: A process for upgrading a feedstream, said process comprising: (a) solvent deasphalting, under solvent deasphalting conditions, said feedstream to obtain a first product stream comprising deasphalted oil and a second product stream comprising asphalt product; (b) slurry hydroprocessing said asphalt product in a slurry hydroprocessing unit under slurry hydroprocessing conditions to obtain a hydroprocessed product; and (c) separating an upgraded oil from the hydroprocessed product and unconverted asphaltene bottoms.

Abstract: The present invention is a process to remove a +2 ionic charged, organically bound metal from a petroleum feed. The process includes contacting feed with aqueous carbon dioxide in the essential absence for emulsion formation.

Abstract: The invention relates to processes for treating acidic crudes of fractions thereof to reduce or eliminate their acidity and corrosivity by addition of suitable amounts of Group IA of Group IIA oxides, hydroxides and hydrates. The process has the additional benefits of reducing materials handling problems associated with treating acidic crude oils using liquid solvents and in reducing emulsion formation.

Abstract: A composite material is provided comprising an elastomer, from about 0.1 wt % to about 15 wt. % of a layered mineral based on the weight of the total composition and from about 0.1 wt. % to about 15 wt. % of asphalt based on the weight of the total composition.

Abstract: The production of liquid hydrocarbons from coal via liquefaction is enhanced by recovering a bottoms fraction from the coal liquefaction reaction and subjecting the bottoms fraction to alkylation or acylation prior to recycling this bottoms fraction to the liquefaction reaction zone. The introduction of aliphatic hydrocarbon radicals or acyl radicals, including carbon monoxide, into the highly refractory molecules of the bottoms product from coal liquefaction permits additional amounts of the coal to undergo liquefaction at suitable liquefaction conditions.
