Abstract: A method for producing hydrogen and carbon from hydrocarbons in a reaction chamber is provided. The method includes introducing a hydrocarbon into a chamber such that the hydrocarbon rotates in a first direction. The method includes generating a direct current (DC)-based plasma from a portion of the hydrocarbon, wherein the hydrocarbon is heated to a temperature greater than 1,000° C. at least in part by the DC-based plasma. The method includes rotating the DC-based plasma in a second direction that is different from the first direction. The method includes converting the hydrocarbon into elemental constituents of the hydrocarbon comprising carbon solid and hydrogen gas. The method includes separating the carbon solid from the hydrogen gas to provide a solid part and a gas part.
