Title (EN) METHODS FOR TREATING AN OFFGAS CONTAINING CARBON OXIDES
(FR) PROCÉDÉ DE TRAITEMENT D'UN DÉGAGEMENT GAZEUX CONTENANT DES OXYDES DE CARBONE
Abstract:
(EN) A method of treating an offgas includes purifying the offgas to remove particulate matter, water, undesirable gaseous components and inert gases to produce a dried carbon oxide gas feedstock, and converting at least a portion of carbon oxides in the dried carbon oxide gas feedstock into solid carbon. In other embodiments, a method includes passing a dried carbon oxide gas feedstock through a multi-stage catalytic converter. A first stage is configured to catalyze methane-reforming reactions to convert methane into carbon dioxide, carbon monoxide and hydrogen with residual methane. A second stage is configured to catalyze the Bosch reaction and convert carbon oxides and hydrogen to solid carbon and water.
(FR) La présente invention concerne un procédé de traitement d'un dégagement gazeux consistant à purifier le dégagement gazeux pour éliminer la matière particulaire, l'eau, les composants gazeux indésirables et les gaz inertes pour produire une charge gazeuse d'oxyde de carbone sec, et à convertir au moins une partie des oxydes de carbone dans la charge gazeuse d'oxyde de carbone sec en carbone solide. Dans d'autres modes de réalisation, l'invention concerne un procédé consistant à faire passer une charge gazeuse d'oxyde de carbone sec à travers un convertisseur catalytique multi-étages. Un premier étage est conçu pour catalyser des réactions de reformage du méthane pour convertir du méthane en dioxyde de carbone, monoxyde de carbone et hydrogène avec méthane résiduel. Un second étage est conçu pour catalyser la réaction de Bosch et convertir les oxydes de carbone et l'hydrogène en carbone solide et en eau.
