The present invention concerns a device for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of thermal plasma, a process for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of thermal plasma, and the use of a device in a process for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of a process of the invention.

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.

A method of making tailored carbon black in a plasma process. A method of making tailored carbon black in a plasma process is described, including subjecting the carbon black particles during and/or after formation to surface functionalizing agents in a controlled manner so as to impart a degree and/or density of functionalization onto the carbon black particles so as to adapt the particles to a particular pre-intended application.

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.

Carbon nanoparticles made in a one step process. A method of making carbon black nanoparticles is described, including adding a hydrocarbon to a heated gas to produce carbon nanoparticles that are less than 1 micron volume equivalent sphere and have an Lc greater than 3.0 nm. Elastomer composites containing such particles are also described.

The present disclosure provides methods and systems for improving a yield of carbon particles from a carbon particle generating rector. The methods and systems may comprise use of a silicon-containing additive in the carbon particle generating process.

The present disclosure provides systems and methods for making carbon particles. The systems of the present disclosure may include a reactor for pyrolysis of hydrocarbon feedstock to carbon particles. The methods of the present disclosure may include contacting, in a reactor, a non-hydrogenous gas with a hydrocarbon feedstock in presence of a plasma to generate carbon particles and an effluent gas. The effluent gas may comprise hydrogen and the non-hydrogen gas. The method may further include separating at least a portion of the effluent gas into the hydrogen and non-hydrogen gas to obtain a separated gas comprising the non-hydrogenous gas. The separated gas comprising the non-hydrogenous gas may be recycled or otherwise returned to the reactor to generate additional carbon particles and effluent gas.

A process for producing hydrogen and pyrolytic carbon from hydrocarbons may involve converting hydrocarbons into hydrogen and carbon in a reactor at temperatures of 1000 C. or more. The reactor may include two electrodes spaced apart from one another in a flow direction of the hydrocarbons. In a region of the reactor between the electrodes an inert gas component is supplied over an entire reactor cross section. The reactor contains carbon particles in the region between the two electrodes. By introducing an inert gas component over the entire reactor cross section, deposition of carbon in this region of the reactor inner wall is prevented, thus effectively inhibiting the formation of conductivity bridges on the reactor inner wall.

A moving packed bed processing plant using medium temperature heating and superheating of process materials to produce gas and solid products is disclosed. A system may include a reactor, a medium temperature heating section, and a superheating temperature section. A particle preheating section of the reactor preheats a moving packed bed of particles; a high temperature section of the reactor transfers energy to the preheated particles; and a decomposition and reaction section provides heat transfer between the moving packed bed of particles and a feed gas such that a reaction occurs that generates a gaseous product and a solid product. The medium temperature heating section heats gases or particles utilizing gaseous product obtained from the reactor and the superheating section further heats the gases or particles from the medium temperature heating section and provides the superheated gases or particles to the high temperature section of the reactor.

The present invention relates to plasma assisted production of carbon black. Particularly, the present invention relates to a method and a reactor, wherein the carbon black feedstock can be injected in multiply positions in the carbon black reactor to avoid droplets in the plasma zone.
