The present invention relates to a method for producing an impregnated pitch from a petroleum-based raw material and to an impregnated pitch produced using the same, and when the method for producing an impregnated pitch according to the present invention is used, it is possible to produce an impregnated pitch having a high carbonization yield (40 wt % or more) and low quinoline insoluble matter (QI, 2% or less) for improving efficiency of an impregnation process from a petroleum-based raw material. Therefore, when an impregnation process is applied to a carbon compact by using the impregnated pitch according to the present invention, it is possible to remarkably reduce micropores inside the carbon compact, and to produce a carbon compact having physical properties such as excellent electrical conductivity and mechanical strength.

Systems and methods are provided for forming specialty products from hydrotreated FCC fractions. Optionally, the hydrotreated FCC fractions used for forming the specialty products can further include a (hydrotreated) portion of a steam cracker tar fraction. The specialty products that can be formed from hydrotreated FCC fractions include, but are not limited to, carbon blacks, resins, and carbon fibers. A convenient method for forming the hydrotreated FCC fractions can be fixed bed hydrotreatment.

High-purity polycyclic aromatic hydrocarbons (PAHs) and the byproducts thereof, and methods for producing such products are disclosed. The PAHs may comprise an aromaticity index of about 0.65 to about 0.80. The PAHs may have quinoline insolubles and sulfur impurities of less than about 0.1 wt. % each. A tar or pitch comprising the high-purity PAHs and a method of producing such tar or pitch are disclosed. A synthetic graphite comprising high-purity PAHs is also disclosed. A method of making carbon pellets from high-purity PAHs is also disclosed.

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. This can allow for formation of unexpected base stock compositions.

Processes are described for the production of a pitch for use in the manufacture of carbon composite materials. The process comprises the steps of providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 25 ?m in diameter; wherein the PCP has an ash content of less than about 10% m; and combining the PCP with a feedstock for pitch to create a combined blended mixture suitable for thermal reaction followed by distillation to create a resultant pitch. The combined blended mixture comprises at least around 0.1% m and at most around 90% m PCP. Composite materials that find utility as carbon electrodes, particularly electrolytic baked carbon anodes, can be made from combining the pitch and PCP with a filler material, such as a pet coke.
