Method for processing of carbon dioxide contained in an exhaust gas flow to a product suitable for energy production, characterized by the fact that a) the exhaust gas flow, having a temperature in the range of 150 to 170°C and a pH value of around 4, is brought in contact in a drying and cooling chamber with a porous silicate material having a moisture of 15 to 60 %, referred to the dry total weight of the silicate material and an admixed aluminium hydroxide and/or hydrated aluminum oxide to form a basic aqueous medium with a pH value between 10 and 13 and is cooled to a temperature between 30 and 50°C, in which the amount of aluminum hydroxide and/or hydrated aluminum oxide to be added is controlled via a continuous pH value measurement, and in which the aqueous medium is cooled until the exit from the drying and cooling chamber to a temperature between 12 and 13°C, b) the aqueous medium is fed to a subsequent prechamber, which is supplied with material containing oxidizable alkaline earth and/or heavy metal, in which oxidation of alkaline earth and/or heavy metal by the oxygen resulting from the ionized and destabilized carbon dioxide, with accompanying neutralization of the aqueous medium containing ionized carbon takes place; and the formed alkaline earth and/or heavy metal oxide is discharged from the prechamber, in which material containing oxidizable alkaline earth and/or heavy metal is simultaneously supplied as a function of continuous pH value measurement and c) the aqueous medium containing ionized carbon is then fed to a main chamber supplied with material consisting of organic carbon compounds and/or containing organic carbon compounds, in which polyreactions with organic carbon compounds occur with participation of the ionized carbon at temperatures between 5 and 80°C and a pressure between 0,1 and 10 bar, to form a carbon-enriched end product. a) the exhaust gas flow, having a temperature in the range of 150 to 170°C and a pH value of around 4, is brought in contact in a drying and cooling chamber with a porous silicate material having a moisture of 15 to 60 %, referred to the dry total weight of the silicate material and an admixed aluminium hydroxide and/or hydrated aluminum oxide to form a basic aqueous medium with a pH value between 10 and 13 and is cooled to a temperature between 30 and 50°C, in which the amount of aluminum hydroxide and/or hydrated aluminum oxide to be added is controlled via a continuous pH value measurement, and in which the aqueous medium is cooled until the exit from the drying and cooling chamber to a temperature between 12 and 13°C, b) the aqueous medium is fed to a subsequent prechamber, which is supplied with material containing oxidizable alkaline earth and/or heavy metal, in which oxidation of alkaline earth and/or heavy metal by the oxygen resulting from the ionized and destabilized carbon dioxide, with accompanying neutralization of the aqueous medium containing ionized carbon takes place; and the formed alkaline earth and/or heavy metal oxide is discharged from the prechamber, in which material containing oxidizable alkaline earth and/or heavy metal is simultaneously supplied as a function of continuous pH value measurement and c) the aqueous medium containing ionized carbon is then fed to a main chamber supplied with material consisting of organic carbon compounds and/or containing organic carbon compounds, in which polyreactions with organic carbon compounds occur with participation of the ionized carbon at temperatures between 5 and 80°C and a pressure between 0,1 and 10 bar, to form a carbon-enriched end product.
