| This invention relates to a dearomatized asphalt. More particularly, an asphalt is extracted with a aromatic extraction solvent to produce an asphalt-rich phase and a solvent rich phase. The asphalt rich phase is stripped of solvent to produce dearomatized asphalt that has superior properties for paving and roofing applications. | ||||||

| PURPOSE: To produce the title pitch having a low softening point, a high mesophase content, a low quinoline-insoluble matter content and a low xylene-soluble matter content, by heating a specified high-molecular bitumen under a reduced pressure or in an inert gas stream. CONSTITUTION: Coal or petroleum heavy oil or a heavy oil component obtd. by distilling or heat-treating said heavy oil is added to a monocyclic arom. hydrocarbon solvent in an amount of 1W3 times that of the heavy oil. The resulting insoluble matter is removed by centrifugation or filtration. The monocyclic hydrocarbon is then removed by distillation to obtain the purified heavy oil or heavy component. The purified product is then heated at 450W550°C under a pressure of 4W50kg/cm 2G and at a residence time of 30W1,000sec in a tubular heating oven in the presence or absence of arom. oil which is used in an amount of 0W1 time as much as that of said purified product and in which no matter insoluble in the monocyclic arom. hydrocarbon solvent is formed when heat-treated at 200W450°C. The monocyclic arom. hydrocarbon solvent in an amount of 1W3 times that of the purified heavy oil is added thereto. The resulting insoluble matter is removed to obtain a high-molecular bitumen. The bitumen is heated in the presence of a hydrogen-donating solvent, hydro genated and then heated under a reduced pressure or in an inert gas stream. COPYRIGHT: (C)1987,JPO&Japio | ||||||

| PURPOSE: To provide a pitch capable of producing therefrom a uniform carbon fiber having excellent strength and modulus of elasticity which is low in softening point, viscosity and mesophase content, by subjecting a carbonaceous pitch to extraction treatment using a specific organic solvent to obtain an insoluble matter, subjecting the insoluble matter to extraction treatment using another specific organic solvent to obtain a soluble matter and then obtaining a pitch from the soluble matter. CONSTITUTION: A carbonaceous pitch is heat-treated at 340W500°C for 1minW30hr while an inert gas such as N 2 is passed through the carbonaceous pitch at a flow rate of 0.7W5.0scfh/lb of the carbonaceous pitch to thereby obtain a pitch having 5W100% of an optically anisotropic region. 1pt. of the obtained pitch is subjected to extraction treatment using 10W150pts. of an organic solvent having a solubility parameter of 7.4W9.0 (for example, cyclohexane) at 15W230°C under atmospheric or applied pressure to obtain an insoluble matter. Then, the above-obtained insoluble matter is subjected to extraction treatment using an organic solvent having a solubility parameter of 9.2W11.0 (for example, nitrobenzene) under the same conditions as mentioned above to obtain a soluble matter. From the obtained soluble matter is a pitch for a carbon fiber having 5W40% of optically anisotropic region is attained. COPYRIGHT: (C)1986,JPO&Japio | ||||||

| Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point. | ||||||

| The invention concerns a method (100) for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps: —supplying (101) a reactor (11) inside which at least two electrodes (13) extend with the bituminous product and a liquid medium of which at least one liquid component has Hansen solubility parameters δη, δρ and δd such that the bitumen is at least partially soluble in the liquid medium, the elements to be separated being insoluble, —generating (102) a series of electromagnetic pulses between the electrodes (13) in the reactor (11) so as to produce, as a result of the power, the frequency and the switching time of the electromagnetic pulses, at least one shock wave and at least ultraviolet radiation, in such a way as to disperse and dissolve the bitumen in the liquid medium, and to separate the bitumen and the insoluble elements, the liquid medium preventing the reconstitution of the bitumen. | ||||||

| A binder for making metallurgical coke and a process for making the binder. The binder is thermally hydrocracked pitch which has been de-ashed. The binder may be mixed with low rank bituminous coal, heated to make coke which is acceptable as a metallurgical coke. The thermally hydrocracked pitch may be de-ashed by mixing with a solvent, and separating the insoluble portions from the soluble portions using a centrifuge. The soluble portions may be separated from the solvent, for example, in a fractionating section, and used as the binder with poor coking coal to make metallurgical coke. | ||||||
