Method for producing hydrogen, comprises transferring elements containing carbon, oxygen and hydrogen existed in dissolved form in a reaction system into a reactor by liquid phase reaction

摘要

The method for producing hydrogen (2), comprises transferring elements (10) containing carbon, oxygen and hydrogen existed in dissolved form in a reaction system (3) into a reactor by liquid phase reaction, where a carbon dioxide formed during the transformation is dissolved in the reaction system, stripping a part of the reaction system loaded with carbon dioxide from the reactor and then replacing by unloaded components (1, 4) of the reaction system so that the carbon dioxide concentration in the reaction system remains always below the solubility limit of the carbon dioxide. The method for producing hydrogen (2), comprises transferring elements (10) containing carbon, oxygen and hydrogen existed in dissolved form in a reaction system (3) into a reactor by liquid phase reaction, where a carbon dioxide formed during the transformation is dissolved in the reaction system, stripping a part of the reaction system loaded with carbon dioxide from the reactor and then replacing by unloaded components (1, 4) of the reaction system so that the carbon dioxide concentration in the reaction system remains always below the solubility limit of the carbon dioxide. The part of the reaction system stripped from the reactor is transported for the separation of carbon dioxide and the recovery of its components into a regenerating device from which the component (9) loaded with carbon dioxide is completely or partially recirculated into the reactor. The separation of carbon dioxide is carried out through temperature increase and/or pressure reduction and/or through stripping. The separation of carbon dioxide is carried out in a pressure that is higher than the critical pressure and in a temperature that is higher than the critical temperature of the dissolved carbon dioxide. The heat is supplied in direct contact with condensing water vapor to the reaction system and/or the mixture to be regenerated. The liquid phase reaction is carried out in a reaction system that has an ionic liquid. An independent claim is included for a device for producing hydrogen.
