Abstract

La présente invention concerne un procédé pour séparer par adsorption du dioxyde de carbone et de l'eau à partir d'un mélange gazeux riche en monoxyde de carbone et en hydrogène, et contenant du dioxyde de carbone et de l'eau. Selon l'invention, le mélange gazeux riche en monoxyde de carbone et en hydrogène est purifié dans une première couche d'adsorption d'eau contenant un gel de silice, et dans une seconde couche d'adsorption de dioxyde de carbone contenant un filtre moléculaire, et la régénération des deux couches d'adsorption s'effectue au moyen d'un mélange gazeux/d'un gaz riche en monoxyde de carbone, sa température valant de 70 à 150 °C. L'invention a également pour objet un procédé analogue pour séparer par adsorption du dioxyde de carbone et du méthanol.
