Abstract
(EN)
The present invention relates to a bifunctional catalyst for preparing a hydrocarbon from carbon dioxide and hydrogen, the bifunctional catalyst comprising: a carbon composite comprising cobalt (Co) and nitrogen (N) atoms coordinated to the cobalt; and metal particles, which exhibit catalytic activity of Fischer-Tropsch synthesis reaction, dispersed on the inner pore surface and/or the outer surface of the carbon composite support, and thus the present invention simultaneously promotes a reverse water gas shift reaction and a Fischer-Tropsch synthesis reaction.
(FR)
La présente invention concerne un catalyseur bifonctionnel pour la préparation d'un hydrocarbure à partir de dioxyde de carbone et d'hydrogène, le catalyseur bifonctionnel comprenant : un composite de carbone comprenant du cobalt (Co) et de l'azote (N) atomes coordonnés au cobalt; et des particules métalliques, qui présentent une activité catalytique de réaction de synthèse Fischer-Tropsch, dispersées sur la surface de pore interne et/ou la surface externe du support composite de carbone, et ainsi la présente invention favorise simultanément une réaction de conversion de gaz d'eau inverse et une réaction de synthèse Fischer-Tropsch.
