▎ 摘　　要

NOVELTY - Production of solid carbon from carbon dioxide gas and water, involves receiving carbon dioxide and water in a reactor to generate a plasma, dissociating carbon dioxide and water using the plasma to form one or more dissociated species, exposing the dissociated species to an electric field to facilitate one or more chemical reactions, generating solid carbon via the chemical reactions, and outputting the solid carbon from the reactor. USE - Production of solid carbon e.g. carbon black, carbon nano-onions (CNOs), necked CNOs, carbon nanospheres, graphite, pyrolytic graphite, graphene, graphene nanoparticles, graphene platelets, fullerenes, hybrid fullerenes, single- walled nanotubes, and multi- walled nanotubes used in composition of matter (all claimed). ADVANTAGE - The method prevents carbon dioxide generated from combustion at fossil fuel-fired electricity generation plants from entering the biosphere, attempts to recapture such greenhouse gases after release into the biosphere, and provides high-efficiency carbon capture for clean fossil fuel power production and yields useful carbon-based byproducts, resulting in an overall negative emissions profile. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: ystem, which comprises a waveguide comprising a plasma zone extending along a length of the waveguide (w1), a microwave energy source coupled to the waveguide and to propagate microwave energy into the waveguide, a flow inlet (f1) to flow carbon dioxide gas into the plasma zone, and a gas-solid separator system coupled to the microwave plasma reactor and is configured to receive multiple components. The microwave energy is configured to generate a plasma within the plasma zone. The plasma is configured to dissociate carbon dioxide gas into multiple components such as oxygen gas and solid carbon particles; and composition of matter, comprises a carbonaceous material having physical characteristics is formed from dissociation of carbon dioxide and water using a plasma and an electric field. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of negative emission reactor coupled to a fossil fuel power production facility and configured to generate useful carbon solid by-products.
