Title
(EN) A PROCESS AND REACTOR FOR CONVERTING CARBON DIOXIDE INTO CARBON MONOXIDE
(FR) PROCÉDÉ ET RÉACTEUR POUR CONVERTIR LE DIOXYDE DE CARBONE EN MONOXYDE DE CARBONE
Abstract
(EN)
The present invention relates to a process for converting carbon dioxide and hydrogen into a product stream comprising carbon monoxide, water and hydrogen, the process comprising introducing carbon dioxide, hydrogen and oxygen into a reaction vessel, and performing a reverse water gas shift reaction at elevated temperature, wherein (a) no catalyst is present in the reaction vessel, and (b) at least a gas stream comprising carbon dioxide, a hydrogen rich gas stream and an oxygen rich gas stream are introduced into the reaction vessel in separate feed streams, wherein the hydrogen rich gas stream is introduced into the reaction vessel at a temperature between 15 and 450 °C, (c) the hydrogen rich gas stream and oxygen rich gas stream being introduced in close vicinity of each other, wherein at least the hydrogen rich gas stream and the oxygen rich gas stream are introduced into the reaction vessel via a burner comprising coaxial channels for the separate introduction of the different gas streams, the burner being located at the top of the reaction vessel, wherein the hydrogen and oxygen in the hydrogen rich gas stream and oxygen rich gas stream undergo a combustion reaction upon entering the reaction vessel, thereby providing the heating energy required for the reverse water-gas shift reaction; and (d) the temperature in the reaction vessel is maintained in the range of 1000 to 1500 °C by varying the molar ratio of hydrogen to oxygen, which are introduced into the reaction vessel in the hydrogen rich gas stream and oxygen rich gas stream, respectively.

La présente invention concerne un procédé de conversion de dioxyde de carbone et d'hydrogène en un flux de produit comprenant du monoxyde de carbone, de l'eau et de l'hydrogène, le procédé consistant à introduire du dioxyde de carbone, de l'hydrogène et de l'oxygène dans une cuve de réaction et à effectuer une réaction de conversion inverse de gaz à l'eau à température élevée, (a) aucun catalyseur n'étant présent dans la cuve de réaction et (b) au moins un flux gazeux comprenant du dioxyde de carbone, un flux gazeux riche en hydrogène et un flux gazeux riche en oxygène étant introduits dans le récipient de réaction en des flux d'alimentation séparés, le flux gazeux riche en hydrogène étant introduit dans la cuve de réaction à une température entre 15 et 450°C, (c) le flux gazeux riche en hydrogène et le flux gazeux riche en oxygène étant introduits à proximité immédiate l'un de l'autre, au moins le flux gazeux riche en hydrogène et le flux gazeux riche en oxygène étant introduits dans la cuve de réaction par l'intermédiaire d'un brûleur comprenant des canaux coaxiaux pour l'introduction séparée des différents flux gazeux, le brûleur étant situé au sommet de la cuve de réaction, l'hydrogène et l'oxygène dans le flux gazeux riche en hydrogène et dans le flux gazeux riche en oxygène subissant une réaction de combustion lors de l'entrée dans la cuve de réaction, fournissant ainsi l'énergie de chauffage requise pour la réaction de conversion inverse de gaz à l'eau; et (d) la température dans la cuve de réaction étant maintenue dans la plage de 1000 à 1500°C par la variation du rapport molaire de l'hydrogène à l'oxygène, qui sont introduits dans la cuve de réaction dans le flux gazeux riche en hydrogène et le flux gazeux riche en oxygène, respectivement.
