Abstract
The embodiments disclosed herein are directed to systems, methods, and devices for pyrolysis of methane in a microwave plasma for hydrogen production and structured carbon powder. Some methods are directed to producing a structured carbon powder using a microwave generated plasma comprising injecting a plasma gas comprising methane (CH4) into a liner, the liner in communication with a microwave waveguide; propagating microwaves through the microwave waveguide, the microwaves generated using a microwave generator; and generating a microwave plasma by contacting the plasma gas with the microwaves.
Claims18
A method for producing a structured carbon powder using a microwave generated plasma, the method comprising:
- injecting a plasma gas comprising methane (CH4) into a liner, the liner in communication with a microwave waveguide;
- propagating microwaves through the microwave waveguide, the microwaves generated using a microwave generator, wherein the microwave waveguide is oriented perpendicular to the liner;
- generating a microwave plasma by contacting the plasma gas with the microwaves;
- directing the microwave plasma through a graphite extension tube, the extension tube extending into a reaction chamber and confining the microwave plasma, and wherein the extension tube tapers radially outwards as it extends into the reaction chamber;
- wherein contacting the plasma gas with the microwaves pyrolyzes the plasma gas into pyrolysis products,
- wherein the pyrolysis products comprise hydrogen gas and solid carbon, and
- wherein the solid carbon comprises a sheet or platelet microstructure.
