Title
(EN) METHANOL PRODUCTION PROCESS
(FR) PROCÉDÉ DE PRODUCTION DE MÉTHANOL
(JA) メタノールの製造方法
Abstract
(EN)
The purpose of the present invention is to provide a methanol production process which can produce methanol from carbon dioxide and hydrogen with high efficiency and can reduce the load on the global environment. This methanol production process comprises the steps of: (a) reacting hydrogen with carbon dioxide in the presence of a copper-containing catalyst in a reactor to produce a reaction mixture containing methanol; (b) circulating a portion or the whole of the reaction mixture through the step (a); (c1) burning a portion of the reaction mixture to produce a burned product and an energy when the reaction mixture contains 0.1 mol% or more (wherein the amount of a component produced by removing methanol and water from the reaction mixture is defined as 100 mol%) of a compound (p) comprising a carbon that is not associated with methanol and hydrogen; (c2) circulating a portion or the whole of the burned product through the step (a); and (d) separating a methanol-containing component from the reaction mixture.

L'objet de la présente invention est un procédé de production de méthanol qui permet de produire du méthanol à partir de dioxyde de carbone et d'hydrogène à une efficacité élevée et peut réduire la charge sur l'environnement global. Ce procédé de production de méthanol comprend les étapes suivantes : (a) réaction de l'hydrogène avec le dioxyde de carbone en présence d'un catalyseur contenant du cuivre dans un réacteur pour obtenir un mélange réactionnel contenant du méthanol ; (b) mise en circulation de tout ou partie du mélange réactionnel dans l'étape (a) ; (c1) combustion d'une partie du mélange réactionnel pour obtenir un produit brûlé et de l'énergie quand le mélange réactionnel contient 0,1 % en mol ou plus (la quantité d'un composant obtenu après élimination du méthanol et de l'eau du mélange réactionnel représentant 100 % en mol) d'un composé (p) comprenant un atome de carbone qui n'est associé ni au méthanol, ni à l'hydrogène ; (c2) mise en circulation de tout ou partie du produit brûlé dans l'étape (a) ; et (d) séparation d'un composant contenant du méthanol à partir du mélange réactionnel.
