Systems and methods for eliminating carbon dioxide and capturing solid carbon are disclosed. By eliminating carbon dioxide gas, e.g., from an effluent exhaust stream of a fossil fuel fired electric power production facility, the inventive concepts presented herein represent an environmentally-clean solution that permanently eliminates greenhouse gases while at the same time producing captured solid carbon products that are useful in various applications including advanced composite material synthesis (e.g., carbon fiber, 3D graphene) and energy storage (e.g., battery technology). Capture of solid carbon during the disclosed process for eliminating greenhouse gasses avoids the inefficiencies and risks associated with conventional carbon dioxide sequestration. Colocation of the disclosed reactor with a fossil fuel fired power production facility brings to bear an environmentally beneficial, and financially viable approach for permanently capturing vast amounts of solid carbon from carbon dioxide gas and other greenhouse gases that would otherwise be released into Earth's biosphere.

Provided is a microwave treatment apparatus that can properly treat a treatment target using microwaves. The apparatus includes: a vessel 10 in which a treatment target 2 is arranged; a microwave irradiating unit 20 that irradiates an internal portion of the vessel 10 with microwaves; and heat generating member 30 that is provided inside the vessel 10 along the treatment target 2, generates heat by absorbing part of microwaves used for irradiation by the microwave irradiating unit 20, and transmits part of the microwaves. The microwave irradiating unit 20 irradiates a portion in which the heat generating member 30 is provided with microwaves, thereby heating the treatment target 2 from the outside through heat generation at the heat generating member 30, and directly heating the treatment target 2 with microwaves transmitted through the heat generating member 30.

In order to provide a chemical reaction apparatus that can suppress a situation where microwaves are concentrated on a partial portion in a reactor, and that can more uniformly irradiate a content with the microwaves, a chemical reaction apparatus includes: a horizontal flow-type reactor in which a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and a waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor, wherein a top of the reactor is curved with respect to a flow direction of the content.

A method and apparatus for the manufacture of nitric oxide and/or nitrogen dioxide in which a plasma is formed from nitrogen and oxygen passed through gas inlets into a reaction chamber to create a vorticular flow in the reaction chamber. A source of microwave energy is used to energise the nitrogen and oxygen in a microwave transparent inner plasma containment

The present invention relates to a method for manufacturing a conductor, and a lithium secondary battery including a conductor manufactured using the manufacturing method, and the method for manufacturing a conductor includes removing metal impurities in a conductor by irradiating microwave on the conductor including the metal impurities and converting the metal impurities into metal oxides.

A conductor manufactured using the manufacturing method converts metal impurities included in the conductor to metal oxides that are inactive at a battery operating voltage and not eluted in an electrolyte liquid, and therefore, is capable of enhancing battery performance properties, particularly, capacity and lifespan properties without concern of metal impurity elution and a defect occurrence under a low pressure caused therefrom.
