Methods and systems of producing chemical feedstocks from crude oil can include: introducing a fraction of crude oil into a catalytic hydrovisbreaker reactor, wherein the crude oil fraction is dealkylated after introduction; introducing a product stream from the catalytic hydrovisbreaker reactor and a solvent into a solvent de-asphalter unit; and introducing de-asphalted oil from the unit into a two-stage hydrocracker to produce the chemical feedstocks. The crude oil fraction can be atmospheric residue or vacuum residue. The chemical feedstocks can include C.sub.3.sup. gases, C.sub.4-C.sub.5 gases, naphtha, BTX, and gas oil. The chemical feedstocks can be used to produce olefins and polymers.

A method for producing pitch can include: hydroprocessing a challenged feed from a refinery operation to produce a hydroprocessed product; distilling the hydroprocessed product to yield one or more upgraded fractions and a resid fraction; and solvent deasphalting the resid fraction to yield a deasphalted oil stream and a hydroprocessed pitch stream. The resultant pitch can have a micro carbon residue (MCR) of 50 wt % or greater, a solubility in toluene of 95 wt % or greater, and a softening point of 200 C. or less. The pitch can optionally be fluxed with a fluxing solvent.

The invention relates to processes for producing anode grade coke from whole crude oil. The invention is accomplished by first deasphalting a feedstock, followed by processing resulting DAO and asphalt fractions. The DAO fraction is hydrotreated or hydrocracked, resulting in removal of sulfur and hydrocarbons, which boil at temperatures over 370 C., and gasifying the asphalt portion in one embodiment. This embodiment includes subjecting hydrotreated and/or unconverted DAO fractions to delayed coking. In an alternate embodiment, rather than gasifying the asphalt portion, it is subjected to delayed coking in a separate reaction chamber. Any coke produced via delayed coking can be gasified.

An apparatus and process for desulfurization of hydrocarbon feeds is disclosed in which pure nitrous oxide, or a mixture of nitrous oxide and oxygen or air, is used as a gaseous oxidant. Organosulfur compounds are converted to their corresponding oxides sulfones and/or sulfoxides in an oxidation reactor, and oxides are subsequently removed from the oxidation reactor effluent to recover a reduced sulfur-content hydrocarbon product.
