Publication number: 20190048200Abstract: 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.

Publication number: 20180022925Abstract: 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.Type: ApplicationFiled: February 1, 2016Publication date: January 25, 2018Applicant: MONOLITH MATERIALS, INC.Inventors: Ned J.
