    摘要： A method of desulfurizing a liquid hydrocarbon having the steps of: adding a liquid hydrocarbon to a vessel, the hydrocarbon having a sulfur content; adding a catalyst and an oxidizer to create a mixture; oxidizing at least some of the sulfur content of the liquid hydrocarbon to form oxidized sulfur in the liquid hydrocarbon; separating the liquid hydrocarbon from the mixture; and removing at least some of the oxidized sulfur from the liquid hydrocarbon. Such methods can be carried out by batch or continuously. Systems for undertaking such methods are likewise disclosed.

    摘要： A fiber bundle contactor may include: a flow path defined by a conduit; a catalytic carbon fiber bundle disposed in the conduit; and an inlet allowing fluid flow into the flow path. A method may include: introducing into vessel a hydrocarbon comprising mercaptan sulfur, an aqueous caustic solution, and an oxidizer; reacting at least a portion of the mercaptan sulfur and the aqueous caustic solution to produce a mercaptide; and reacting the mercaptide and the oxidizer in the presence of a catalytic carbon fiber bundle to produce a disulfide oil.

    摘要： We disclose a process for purification of mixed hydrocarbons, suitable for a wide range of contexts such as separating and recovering mixed polymer materials, refining used oils and fuels, recovery of hydrocarbons from used tyres, recovery of hydrocarbons from thermoplastics etc, to yield clean hydrocarbon distillates suitable for use as recycled feedstocks in chemical industries or as low sulphur fuels for motive use, as well as the treatment of crude oils, shale oils, and the tailings remaining after fractionation and like processes. The method comprises the steps of heating the hydrocarbon bearing material thereby to release a gas phase, contacting the gas with an aqueous persulphate electrolyte within a reaction chamber, and condensing the gas to a liquid or a liquid/gas mixture and removing its aqueous component. It also comprises subjecting the reaction product to an electrical field generated by at least two opposing electrode plates between which the reaction product flows; this electrolytic step regenerates the persulphate electrolyte which can be recirculated within the process. The process is ideally applied in an environment at lower than atmospheric pressure, such as less than 14000 Pa. A wide range of mixed materials and hydrocarbons can be separated and treated in this way. Used hydrocarbons such as mixed plastic packaging waste, industrial polymers, pyrolysis oils etc, are typical examples, but there are a wide range of other materials having a hydrocarbon content. One such prime example is a mix of used rubber (such as end-of-life tyres) and used oils (such as engine oils, waste marine oils) etc, which can be pyrolysed together to yield a hydrocarbon liquid which can be treated as above to provide a carbon black residue that has extensive industrial uses.

    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： A multi-phase process involves physical and chemical methods to recover the oil bases of used oils. The resulting oil base meets the standards and technical specifications necessary for reuse in the formulation of lube oils, greases and alike. The process includes classifying the used oil according to its physicochemical characteristics in order to optimize the subsequent phases. Next, the used oil is subject to physical pre-treatment to remove the solids of about 20 microns, dehydrate them and extinguish the remains of light hydrocarbons. Afterwards, the used oil undergoes extraction with organic chemical solvents on specific proportions within certain pressure and temperature ranges. The output is an extract composed of the oil base, the solvents and a semi-solid precipitate containing the used oil pollutants. Next, the extract is separated from the precipitate by physical methods. Subsequently, the extract passes through another physical procedure that separates the solvents from the oil base.

    摘要： The present application provides systems and methods for upgrading an oil stream. The system includes a reactor, a phase separator, an expansion device, a cooling unit, and two separation units. The reactor receives the oil stream, ammonia, and supercritical water. The supercritical water upgrades the oil stream, and the ammonia reacts with sulfur initially present in the oil stream to produce ammonia-sulfur compounds. The phase separator receives a mixture stream comprising the upgraded oil stream, supercritical water, and the ammonia-sulfur compounds, and separates out non-dissolved components. The expansion device reduces the pressure of the mixture stream below a water critical pressure. The cooling unit reduces the temperature of the mixture stream. A first separation unit separates the mixture stream it into a hydrocarbon-rich gaseous phase, a water stream containing ammonia-sulfur compounds, and a treated oil stream. A second separation unit separates the ammonia-sulfur compounds from the water stream.
