摘要： Systems and methods of making carbon particles with thermal transfer gas. A method of making carbon particles may comprise heating a thermal transfer gas by Joule heating and contacting the thermal transfer gas with a reactive hydrocarbon feedstock gas to generate the carbon particles and hydrogen gas. A method of making carbon particles may comprise heating a thermal transfer gas with the aid of Joule heating and mixing the thermal transfer gas with a hydrocarbon feedstock gas to generate the carbon particles.

摘要： A method and apparatus for making carbon black. A plasma gas is flowed into a plasma forming region containing at least one, magnetically isolated, plasma torch containing at least one electrode, and forming a plasma. Collecting the plasma formed in a cooled header and flowing the plasma through at least one reaction region to heat the reaction region, and injecting carbon black forming feedstock into the reaction region, resulting in the formation of at least one grade of carbon black. An apparatus for making carbon black is also described including a plasma forming section containing at least one, magnetically isolated plasma torch containing at least one electrode, in fluid flow communication with at least one carbon black forming reactor section, the plasma section and reactor section separated by a plasma formed collection header.

摘要： 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.

摘要： A method of cooling a liner in a plasma chamber. A recycle gas is contacted with or passed through the liner to cool the liner and pre-heat the recycle gas. The pre-heated gas is then recycled through the plasma chamber to become part of the plasma forming process. The method further comprises the liner is graphite, the recycle gas passes through at least one cooling channel present in the liner, at least one of the cooling channels are covered with at least one removable liner/channel cover, carbon deposits are formed from the presence of hydrocarbons in the recycle gas, at least one channel is formed in a spiral cooling channel pattern, at least one channel is formed in a substantially straight cooling channel pattern, and a plenum to aid in the production of an even distribution of cooling gas in the channels.

摘要： A method of making carbon black. Such method is described including generating a plasma by subjecting a plasma gas to a plasma arc, mixing a feedstock material with the plasma gas and combining the mixture in a reactor at a given reactor temperature to produce carbon black, wherein the feedstock is mixed with the plasma gas outside of the area occupied by the plasma arc. The carbon black produced by such process is also described.

摘要： 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.
