Aspects of the present disclosure involve a plasma reactor system that includes a gas-flow-engineered reactor to more efficiently produce fixed nitrogen products. In some instances, the gas-flow-engineered reactor may include a gas vortex-inducing input mechanism and/or a quenching mechanism integrated or otherwise associated with the plasma reactor system.
A system for producing fixed nitrogen products includes a header coupled to one or more plasma torch reactors. The plasma torch reactors receive input gases and generate (e.g., using microwave energy) a plasma and resulting reactive nitrogen species. The reactive nitrogen species oxidize within the header, resulting in a product stream. In certain implementations, the product stream is transported to an absorption unit for conversion into the fixed nitrogen products. Certain implementations include cooling, supplemental fluid, and other systems to vary and enhance production of fixed nitrogen products and operation of the system.

Aspects of the present disclosure involve a power supply circuit for powering a plasma reactor and more specifically initiating and maintain a plasma therein, and that can operate with power from an intermittent power source. The power supply may include an auxiliary-power supply or trigger circuit, in addition to a primary-power supply circuit, which can reduce the need for high-voltage equipment in the high-power section of the power supply. In one particular use, the power supply includes a high-voltage power output that may be used for generating a plasma between electrodes, for example, in a nitrogen-fixation plasma system. The power supply circuit may provide the flexibility to power a plasma reactor using an intermittent power source, such as solar, wind, and/or a periodic low-cost power grid, while reducing wasteful power conditioning, lowering the cost of operation, and increasing the efficiency of chemical production from the renewable energy.
