A variety of methods/systems/apparatus/compositions are disclosed, including, in one embodiment, a method including introducing a polymeric material, an unsaturated compound, and an olefin cross metathesis catalyst into a reactor, wherein the polymeric material comprises a carbon black filler; reacting at least a portion of the polymeric material with the unsaturated compound in the presence of the olefin cross metathesis catalyst to produce at least metathesis oil and metathesis carbon black, wherein the metathesis oil comprises an olefin cross metathesis product of the polymeric material and the unsaturated compound; and separating at least a portion of the metathesis carbon black.

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.

The present invention relates to a process for the production of carbon black from a plastic pyrolytic char. In particular, the process comprises pre-washing the plastic pyrolytic char followed by washing with acid and then base.

The present technology generally relates to a method for recovering carbon black (rCB) from a vulcanized polymer matrix, the method comprising performing oxidative desulfurization of the vulcanized polymer matrix with an aqueous chloramine solution. The present technology also relates to compositions comprising rCB obtained from the methods defined herein.

The invention relates to a method for producing hydrogen gas and optionally a carbonaceous product from a hydrocarbon fuel, comprising: introducing a flowing stream of said fuel into a reaction chamber of a reactor, wherein said reaction chamber has at least one wall and a heating zone which is heated by a heat source, heating said fuel in said heating zone to effect pyrolytic decomposition of said hydrocarbon fuel to produce said hydrogen gas and optionally said carbonaceous product; wherein the ratio of C:O (mol/mol) in the reaction chamber is greater than 20:1; and characterized in that the heat source heats the hydrocarbon fuel in the heating zone by radiated heat to an average temperature of greater than 2000 C.

The invention also relates to an apparatus for carrying out the method of the invention.

A gas turbine system includes a turbine combustor, a turbine, an exhaust gas compressor, an exhaust gas recirculation (EGR) system, a carbon black recovery system, and a carbon black production controller. The carbon black production controller monitors data corresponding to a parameter of the carbon black. The carbon black production controller is also configured to adjust, based on the data, the fuel provided to the turbine combustor while maintaining a ratio of the fuel to the oxidant within a predetermined range to adjust the parameter of the carbon black.

The disclosed is a method for producing a carbon material dispersion which removes efficiently and reliably metallic components from carbon materials, and that provides a carbon material dispersion of a high product quality and stable electrical properties. The method comprises a first magnetic separation step in which the powdered and/or granulated carbon material C is applied to the surface of a rotating magnetic roll 130 to remove the metallic component M from the carbon material in the dry state of the powdered and granulated carbon material C; and a second magnetic separation step in which a magnet element 310 is placed in a carbon material dispersion D, in which the carbon material from which the metallic component has been removed in the first magnetic separation step is dispersed in a dispersing medium, in advance of the second magnetic separation step.
