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.
An enclosed particle generating reactor comprising a plasma generating section containing one or more sets of plasma generating electrodes, connected to a reactor section containing hydrocarbon injectors, the interior dimension of the reactor section being reduced by at least 10% downstream from the plasma generating electrodes, and the hydrocarbon injectors being either at the point of maximum reactor size reduction or further downstream from the plasma generating electrodes.
A method of making carbon black particles in an enclosed particle generating reactor, comprising generating a plasma comprising at least 60% by volume hydrogen with plasma generating electrodes in a reactor, reducing the interior dimension of the reactor by at least 10% downstream of the plasma generating electrodes, and injecting hydrocarbon either at the point of maximum reactor size reduction or further downstream from the plasma generating electrodes to form carbon black particles.
