Description

technical field [0001] The invention relates to a low-carbon hydrocarbon reforming hydrogen production device, more specifically, the invention relates to a cooperatively driven rotating sliding arc discharge plasma reforming methane hydrogen production device. Background technique [0002] Converting methane into hydrogen for use can not only realize the clean utilization of methane and reduce greenhouse gas emissions, but also meet the corresponding industrial needs and improve energy grade. At present, the main technology used to produce hydrogen from methane is steam reforming of hydrocarbons to produce hydrogen, but this technology uses a strong endothermic reaction, the reaction temperature is high, and external heat must be supplied, and the thermal efficiency is low; a large amount of water is excessive in the reaction process, energy The consumption is high, resulting in waste of energy and resources; it is necessary to promote the reaction under the action of a cat...

Problems solved by technology

[0004] However, the plasma area formed by the sliding arc discharge of the traditional blade electrode is approximately two-dimensional, the reaction area is small, a large number of reactants do not pass through the plasma area, and the residence time of the reactants is short, and the arc needs to be repeated continuously from breakdown The process from arc initiation to arc elongation to final extinction, so the treatment effect is limited
