Abstract: In a first stage of a methane conversion system, at least some methane (CH4) in an input gas flow stream can be converted into C2 hydrocarbons, hydrogen gas (H2), and aromatics to provide a first processed stream. The conversion can be direct non-oxidative methane conversion (DNMC). At least some of the aromatics can be removed from the first processed stream to provide a second processed stream. In a second stage of the methane conversion system, at least some of the H2 can be removed from the second processed stream to provide a recycle stream. The recycle stream can be returned to the first stage of the methane conversion system for further conversion of methane and removal of aromatics and H2 products.

Abstract: One or more reactants are flowed into thermal contact with a heating element in a reactor for a first time period. During a first part of a heating cycle, the one or more reactants are provided with a first temperature by heating with the heating element, such that one or more thermochemical reactions is initiated. The one or more thermochemical reactions includes pyrolysis, thermolysis, synthesis, hydrogenation, dehydrogenation, hydrogenolysis, or any combination thereof. The first heating element operates by Joule heating and has a porous construction that allows gas to flow therethrough. During a second part of the heating cycle, the one or more reactants are provided with a second temperature less than the first temperature, for example, by de-energizing the heating element. A duration of the first time period is equal to or greater than a duration of the heating cycle, which is less than five seconds.
