  • Patent number: 11865521
    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.

  • Patent number: 11658307
    Abstract: The present disclosure relates to a method and an apparatus for manufacturing a core-shell catalyst, and more particularly, to a method and an apparatus for manufacturing a core-shell catalyst, in which a particle in the form of a core-shell in which the metal nanoparticle is coated with platinum is manufactured by substituting copper and platinum through a method of manufacturing a metal nanoparticle by emitting a laser beam to a metal ingot, and providing a particular electric potential value, and as a result, it is possible to continuously produce nanoscale uniform core-shell catalysts in large quantities.

  • Publication number: 20210230005
    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.

  • Patent number: 10722859
    Abstract: To provide a reactor to improve evenness in the thickness of shell metals coated on the surface of core particles by increasing area sizes in the reactor chamber to control electric potentials, the present invention is configured to comprise a top surface able to move up and down while serving as a working electrode, a wall serving as a working electrode, a bottom surface, a standard electrode, a power supplying part and a solution injecting part, wherein the top surface can move up and down automatically by an electric motor or manually. Also, the top surface is configured to be suitable for the interior diameter of the reactor chamber, for solutions inside the reactor chamber not to leak from the top surface or from the crevice between the top surface and the wall of the reactor chamber. The bottom surface of the reactor chamber may comprise an impeller or an ultrasonic wave diffuser to bring about even diffusion in the reactor chamber.
