Abstract

La présente invention a pour objet un procédé de préparation d'un gaz riche en méthane. Elle est caractérisée en ce qu'on associe un courant de gaz de synthèse préchauffé comprenant pratiquement uniquement de l'hydrogène et du monoxyde de carbone en un rapport volumique 3/1, à un courant de recyclage provenant d'un réaction de méthanation, en ce qu'on fait passer ce courant associé sur un lit nickeliferreux de catalyseur de méthanation dans un réacteur de méthanation, en ce qu'on améliore le rapport de recyclage grâce au maintien de la température du courant d'entrée combinée à une valeur comprise entre 75 et 250 degrés C, et en ce que pour éviter la destruction du catalyseur on dispose une couche de catalyseur de déplacement dans le réacteur de méthanation juste avant le catalyseur de méthanation. Elle se rapporte à la production d'un gaz riche en méthane remplaçant le gaz naturel.
