  • Patent number: 11939477
    Abstract: A high temperature heat integration method of making carbon black. A method of making carbon black is described, including reacting a carbon black forming feedstock with hydrogen gas in a plasma reactor to produce effluent gas containing carbon black and unused hydrogen, cooling the effluent gas for further processing, and recycling the unused hydrogen back into the carbon black forming process, where the unused hydrogen gas is pre-heated in a heat exchanger to a temperature up to the reaction temperature in the reactor before being recycled into the carbon black forming process. The heat exchanger for use in such process is also described.

  • Patent number: 11203692
    Abstract: A method and apparatus for making carbon black having increased surface area, reduced grit and/or reduced extract levels. A plasma gas is flowed into a plasma forming region to form a plasma. The plasma then flows through a throat region which is narrower than the plasma forming section, which is connected to a separate carbon black forming region. This causes the plasma to accelerate and become turbulent prior to the exit point in the throat region. The carbon black forming feedstock is injected into the turbulence created by the throat region at a point above, at or near the exit point, resulting in the formation of a carbon black in the separate carbon black forming region. The throat region and/or injector region can be cooled, e.g., water plasma gas cooled.

  • Publication number: 20190048200
    Abstract: A method of making carbon black. A method of making carbon black is described including combusting feedstock with plasma in an apparatus having a series of unit operations with individual capacities. The individual capacities of the unit operations are substantially balanced by replacing at least part of the feedstock with a feedstock having a molecular weight heavier than methane. This results, among other things, in increased utilization of the individual capacities of the unit operations and increased overall throughput.
