METHOD OF PRODUCTION OF HYDROGEN AND METHANOL Russian patent published in 2006 - IPC C01B3/38 C07C31/04 

FIELD: chemical industry; methods of production of hydrogen and a methanol.

SUBSTANCE: the invention is pertaining to the method of production of the industrial hydrogen and methanol from the converted gas consisting mainly of CO₂, H₂. The method of production of hydrogen and methanol from the converted gas containing carbon oxides and hydrogen includes the synthesis of methanol. For execution of the methanol synthesis feed the converted gas with the volumetric ratio of H₂-CO₂/CO+CO₂, equal to 2.03-5.4, which is conducted in the reactor system including the flow reactor or the cascade of the floe reactors and / or the reactor with the recycle of the gas mixture with production of methanol, the unreacted gas and the blow-down gas. At that the mixture of the unreacted and converted gases is fed for purification from carbon carbon dioxide with its extraction and batch feeding of the carbon dioxide into the converted gas delivered for the synthesis of methanol. The blow-down gases are subjected to the fine purification from the impurities with production of hydrogen. The invention allows to upgrade the method due to maximum usage of the carbon dioxide.

EFFECT: the invention ensures improvement of the method of production of hydrogen and a methanol due to maximum usage of the carbon dioxide.
