Title
(EN) PRODUCTION OF HYDROGEN VIA A BASE-FACILITATED REACTION OF CARBON MONOXIDE
(FR) PRODUCTION D'HYDROGENE FACILITEE PAR UNE REACTION DE MONOXYDE DE CARBONE AVEC UNE BASE
Abstract
(EN)
A method of producing hydrogen gas from a reaction of carbon monoxide with a base. Hydrogen is produced in a reaction of a base with carbon monoxide that proceeds through the formation of a bicarbonate or carbonate compound as a by-product. In some embodiments, the reaction may occur in the presence of water and may produce carbon dioxide as a by-product. The instant base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous than the water-gas shift reaction and are able to produce hydrogen gas from carbon monoxide at greater reaction rates than is possible with the water-gas shift reaction. Carbon monoxide in a purified or unpurified state or as a component within a mixture of gases is suitable for use in the instant invention. Metal hydroxides are the preferred base reactant. The base reactant can be in the solid phase, molten phase, liquid phase or solution phase.

La présente invention a trait à un procédé de production de gaz hydrogène à partir d'une réaction de monoxyde de carbone avec une base. L'hydrogène est produit dans une réaction d'une base avec du monoxyde de carbone qui comprend la formation d'un composé bicarbonate ou carbonate comme sous-produit. Dans certains modes de réalisation, la réaction peut être effectuée en présence de l'eau et peut produire du dioxyde de carbone comme sous-produit. Les réactions de production d'hydrogène facilitées par une base sont d'une thermodynamique plus spontanée que la conversion eau/gaz et peuvent produire du gaz hydrogène à partir du monoxyde de carbone à des taux de réaction supérieurs à ce qui est possible avec la conversion eau/gaz. Du monoxyde de carbone dans un état purifié ou non purifié ou sous la forme d'un constituant au sein d'un mélange de gaz est apte à être utilisé dans la présente invention. Des hydroxydes métalliques constituent le réactif de base préférés. Le réactif de base peut être en phase solide, en phase fondue, en phase liquide ou en phase soluble.
