Abstract: The present disclosure relates to a device for gas conversion comprising a plasma reactor and a chamber configured for receiving a gas flow of converted and unconverted feed gas evacuated from the plasma reactor. The chamber comprises a supply throughput for filling the chamber with solid reactant material so as to form the fixed bed of solid reactant material, and at least one gas exhaust window for extracting a product gas. The device for gas conversion further comprises a silo for storing a stock of the solid reactant material and a connecting tube connecting a bottom opening of the silo with the supply throughput of the chamber. The silo and the connecting tube are configured such that, when the device is in operation and solid reactant material is being depleted in the chamber, a flow of solid reactant material from the silo to the chamber is induced so as to maintain the chamber filled with solid reactant material, and wherein the flow of solid reactant material from the silo to the chamber is induced by a gravitational force or at least partly by a gravitational force. The present disclosure also relates to a method for gas-conversion.

Abstract: The present invention concerns a method for producing carbon monoxide (CO), comprising the steps of: providing a gaseous initial input stream comprising carbon dioxide (CO2) to a plasma zone: at least partially converting said CO2 to CO by: (a) igniting a plasma in the plasma zone: (b) extracting an output stream from the plasma zone, said output stream comprising less CO2 than said first stream, and recycling said output stream as a gaseous input stream to said plasma zone and further converting CO2 to CO by performing steps (a) and (b), thereby obtaining a final output stream comprising more CO and less CO2 than the initial input stream.

Abstract: A system and method for converting carbon dioxide are proposed. The system for converting carbon dioxide includes a carbon monoxide generator for generating carbon monoxide through a reverse water gas shift reaction and a hydrocarbon generator for producing a hydrocarbon through a Fischer-Tropsch synthesis reaction, whereby the carbon monoxide generator is packed both with a catalyst for the reverse water gas shift reaction and with a catalyst for the Fischer-Tropsch synthesis reaction, thus increasing the CO yield in the carbon monoxide generator even at a low temperature compared to when the catalyst for the reverse water gas shift reaction is used alone, ultimately increasing the hydrocarbon yield in the hydrocarbon generator. Moreover, the energy of the exothermic Fischer-Tropsch synthesis reaction can be used as the energy required for the endothermic reverse water gas shift reaction, thereby increasing energy efficiency and processing yield and thus reducing operation and maintenance costs.

Abstract: A composition of a photocatalyst, a method of manufacturing the photocatalyst, and a method of chemically reducing carbon dioxide to carbon monoxide using the photocatalyst under visible-light irradiation is provided. The photocatalyst comprises a transition metal ion and graphitic carbon nitride and includes single metal sites on carbon nitride. Under visible light, the metal sites that are coordinated to nitrogen atoms get activated, without the use of additional ligands, to catalyze the reduction of carbon dioxide to selectively produce carbon monoxide. The photocatalytic reduction of carbon dioxide to carbon monoxide is highly efficient, resulting a turnover number of more than 800 for carbon monoxide production in 2 hours. The composition is useful in converting carbon dioxide into useful chemicals and carbon-based fuels. A functional model of molecular catalysts for efficient carbon dioxide reduction is also present.

Abstract: Improvement in the efficiency of carbon dioxide reduction reaction is achieved. A gas supply unit having a plurality of pores is established in a lower portion of a reduction chamber, and carbon dioxide is supplied as bubbles into an aqueous solution. This can elevate a concentration of carbon dioxide dissolved in the aqueous solution without stirring the aqueous solution using a stirring bar, and render the concentration uniform in the aqueous solution. Therefore, the efficiency of reduction reaction of carbon dioxide in a reduction electrode can be improved.
