Abstract (en)
[origin: WO2022087708A1] A method for producing hydrogen and carbon powder from the plasma pyrolysis of hydrocarbons is disclosed and includes a DC n on-transferred electric arc plasma torch, a hot-wall reactor, for example lined with refractory or a graphite (slippery material), and a cyclone. The cyclone is adapted to recover heavier carbon particles and allow part of the hydrogen, unconverted hydrocarbon and lighter carbon particles to be recycled to the reactor to improve the overall yield of hydrogen. The prolonged contact with the plasma plume provides a typically complete conversion to hydrogen and carbon powder due to the hot walls of the reactor. The carbon powder leaving the plasma plume solidifies into a graphite- like powder in the reactor. A turbulence inside the reactor is adapted to prevent the buildup of soot on a reactor surface via the recycling of hydrogen, hydrocarbon gas or carbon powder or a mix of thereof to the reactor.
