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.
