Abstract

Procédé pour améliorer le pouvoir calorifique d'un mélange d'oxyde de carbone et d'hydrogène. On introduit ce mélange dans un lit fluidisé de fer et de carbure de fer à des températures et des pressions telles qu'une partie de l'oxyde de carbone est réduite en carbone qui réagit avec le fer avec formation de carbure de fer, lequel réagit avec l'hydrogène avec formation de méthane et régénération du fer, et on évacue en continu du lit fluidisé le mélange gazeux résultant consistant en méthane, oxyde carbone et hydrogène. Le procédé selon l'invention permet d'augmenter à peu de frais le pouvoir calorifique d'un gaz dans une proportion pouvant atteindre et dépasser 30 %.
