Abstract: Apparatus and process for the continuous production of carbon black or carbon containing compounds. The process is performed by converting a carbon containing feedstock, including generating a plasma gas with electrical energy, accelerating the plasma gas through a nozzle, whose diameter is narrowing in the direction of the plasma gas, guiding the plasma gas into a reaction area where feedstock is injected under conditions generated by aerodynamic and electromagnetic forces, including intense rapid mixing between the plasma gas and feedstock occurs. There is no significant recirculation of feedstock into the plasma chamber, and the reaction zone does not immediately come into contact with any contact surfaces. The products of reaction are cooled, and the carbon black or carbon containing compounds are separated from the other reaction products.

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.

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.

Abstract: Secondary heat may be added to a particle production process. The particles may be, for example, carbon particles. Among other things, the secondary heat addition may result in change in surface area of the carbon particle(s), change in structure of the carbon particle(s), reduced wall fouling, reduced energy consumption and/or increased throughput. Apparatus for performing the process is also described.

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.
