Abstract
L'invention concerne un appareil pour produire un gaz composite contenant du monoxyde de carbone et de l'hydrogène. L'appareil pour produire le gaz composite contenant du monoxyde de carbone et de l'hydrogène selon l'invention comprend: un premier dispositif de prétraitement pour un gaz dérivé de la ferronnerie contenant du méthane; un second dispositif de prétraitement pour un gaz dérivé de la ferronnerie contenant du dioxyde de carbone, lequel dispositif est placé à distance du premier dispositif de prétraitement; un dispositif générateur de vapeur pour mélanger le gaz dérivé de la ferronnerie contenant du méthane, traité par le premier dispositif de prétraitement et le gaz dérivé de la ferronnerie contenant du dioxyde de carbone traité par le second dispositif de prétraitement, et fournissant de la vapeur aux gaz mélangés; et un dispositif de réaction de reformage conçu pour recevoir et assurer le reformage des gaz mélangés auxquels la vapeur est ajoutée et pour convertir ces gaz en un gaz réduit contenant du monoxyde de carbone.
