摘要： The invention relates to the oil-refining industry, in particular, to methods for purifying a fuel from sulfur-containing compounds, by separating the sulfur-containing modified molecules from the remainder of the fuel molecules on polymer membranes and by activating the fuel purified in the fully-developed cavitation mode prior to the combustion. The reduction of the sulfur content in the fuel is achieved by treating the fuel or a fuel fraction in the fully-developed cavitation mode with addition of a hydrogen peroxide aqueous solution and/or a strong aqueous solution of iron oxides, followed by separating the obtained emulsion into a fuel fraction and a water-paraffin emulsion, followed by separating the fuel fraction on the membranes under the temperature of from 90° C. to 180° C. under atmospheric pressure into a fuel fraction having low sulfur combustion of the purified fuels down to zero by means of activation of the fuels having the low sulfur content.

摘要： An oil desulfurization method may be used to desulfurize various oils, such as used motor oil, crude oil, diesel, high sulfur fuel oil, mid sulfur fuel oil, off-spec fuel oil, and off-spec diesel, to produce a finished product of lower sulfur oil and a high sulfur fuel oil or sulfur containing oil product. Preferably, the method may include the steps of: mixing an oxidizing material with sulfur containing oil to produce a first mixture; subjecting the first mixture to at least one of heat and pressure to oxidize the sulfur in the first mixture; mixing at least one solvent with the first mixture to produce a second mixture; and separating the second mixture to produce a low sulfur oil product and a third mixture, the third mixture having a high sulfur oxidized oil and the at least one solvent.

摘要： A method of producing at least one or more resins is disclosed. The method includes providing an amount of raw coal. The raw coal includes one or more impurities therein. The method also includes beneficiating the amount of raw coal to selectively removing at least a portion of some of the one or more impurities in the raw coal to form beneficiated coal. Additionally, the method includes processing the beneficiated coal to produce an amount of pitch. The method further includes modifying at least some of the pitch to produce the one or more resins. The one or more resins include a selected amount of a remainder of the one or more impurities that were not removed while beneficiating the amount of the raw coal, processing the beneficiated coal, and modifying at least some of the pitch.

摘要： A light naphtha feedstock containing olefins is introduced with hydrogen sulfide into a mercaptanization zone for conversion of the olefins into a mercaptan stream that is substantially free of olefins, after which the mercaptans are sent with an alkali caustic solution into a mercaptan oxidation treatment unit (MEROX) to produce a spent caustic stream and sweet light naphtha product stream that is substantially free of olefins and of mercaptans. Disulfide oils are produced from the wet air oxidation of the spent caustic, and the disulfide oils can be further processed to provide high purity olefin building blocks.

摘要： Embodiments provide a method including: supplying the hydrocarbon feedstock to an oxidation reactor, where the hydrocarbon feedstock is oxidized in the presence of a catalyst to selectively oxidize sulfur compounds present in the hydrocarbon feedstock; separating the hydrocarbons and the oxidized sulfur compounds by solvent extraction; collecting a residue stream that includes oxidized sulfur compounds; supplying the residue stream to a gasifier to produce a syngas stream and a hydrogen sulfide stream; supplying the extracted hydrocarbon stream to a stripper to produce a stripped oil stream, which is then supplied to an adsorption column, such that the adsorption column can produce a high purity hydrocarbon product stream, a second residue stream, and a spent adsorbent stream, the spent adsorbent stream containing another portion of the oxidized compounds; and supplying the spent adsorbent stream to the gasifier to produce additional syngas for the syngas stream, thereby disposing of the adsorbent.

摘要： An oxidative treatment process, e.g., oxidative desulfurization or denitrification, is provided in which the oxidant is produced in-situ using an aromatic-rich portion of the original liquid hydrocarbon feedstock. The process reduces or replaces the need for the separate introduction of liquid oxidants such as hydrogen peroxide, organic peroxide and organic hydroperoxide in an oxidative treatment process.
