Abstract: The present disclosure relates to a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen. The bifunctional catalyst includes a carbon composite including cobalt (Co) and nitrogen (N) atoms forming a coordinate bond with the cobalt, and metal particles which exhibit a catalytic activity for a Fischer-Tropsch synthesis reaction and which are dispersed on the inner pore surface and/or the outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction.

Abstract: The present invention relates to: a catalyst activation method for Fischer-Tropsch synthesis; a catalyst regeneration method for Fischer-Tropsch synthesis; and a method for producing a liquid or solid hydrocarbon by using the Fischer-Tropsch synthesis reaction. The temperatures required for a metal carbide producing and activating reaction is markedly lower than existing catalyst activation temperatures, and the catalyst can be activated under conditions that are the same as Fischer-Tropsch synthesis reaction conditions, and thus there is no need for separate reduction equipment in the reactor, and a Fischer-Tropsch synthesis catalyst which has been used for a long time can be regenerated within the reactor without the catalyst being isolated or extracted from the reactor.

Abstract: The present invention relates to an anti-coking catalyst having a physical property of reducing coke formation, which comprises a solid acid catalyst containing gadolinium (Gd) on the surface, a preparation method thereof, and a use thereof. The preparation method includes a first step of determining the amount of gadolinium (Gd) or a Gd-providing precursor to be used relative to the total weight of the solid acid catalyst, which reducing the coking of a specific solid acid catalyst below a specific level under a specific reaction condition; and a second step of preparing a Gd-containing solid acid catalyst using the amount determined in the first step. The catalyst according to the present invention is a catalyst in which an appropriate weight ratio of gadolinium is supported on the surface of a pure solid acid substance or solid acid substance on which a specific metal is supported. Therefore, the production of coke on the catalyst surface is inhibited while maintaining the activity of the solid acid catalyst in a hydrocarbon conversion reaction, and as a result, the catalyst of the present invention exhibits an effect of improving its lifespan.

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: The present invention relates to a method for producing the activated catalyst for Fischer-Tropsch synthesis comprising: a first step of reducing a catalyst for Fischer-Tropsch synthesis; a second step of preparing liquid hydrocarbon in which a part or all of molecular oxygen is eliminated; and a third step of introducing the reduced catalyst prepared in the first step into the liquid hydrocarbon prepared in the second step while blocking its contact with air. Since the reduced catalyst used for Fischer-Tropsch synthesis is introduced into liquid hydrocarbon from which molecular oxygen is removed or coated by liquid hydrocarbon, the catalyst for Fischer-Tropsch synthesis activated based on the present invention maintains a high activity even if exposed to the air for a long time, thereby easily facilitating the long-term storage and long-distance transfer of the reduced catalyst.
