Abstract: The invention relates to a method for removing and immobilising carbon dioxide (102) from the atmosphere and/or a waste gas (113), comprising the steps of: a) converting the carbon dioxide (102) from the atmosphere and/or a waste gas (113) into biomass (100) by way of photosynthesis, preferably on agricultural surfaces, in particular in a greenhouse (1); b) carrying out a biogas reaction, in which the biomass (100) produced in step a) is converted into biogas (101), containing methane (103) and carbon dioxide (102), in particular in a biogas reactor (2); c) separating the methane (103) from the obtained biogas (101); d) splitting the methane (103) into carbon (106) and hydrogen (110), the carbon (106) being obtained as a solid; e) collecting the obtained carbon (106); f) depositing the obtained carbon (106); and g) reacting carbon dioxide (102) from the biogas with the hydrogen (110) obtained in step d) to form a hydrocarbon mixture.

Abstract: The invention relates to a method for separating off and immobilizing carbon dioxide and/or carbon monoxide from an exhaust gas (18). In the method, a stoichiometric ratio of carbon dioxide to hydrogen, and/or of carbon monoxide to hydrogen, which is suitable for a methanation reaction is set by virtue of a corresponding quantity of hydrogen or alternatively carbon dioxide and/or possibly carbon monoxide being supplied, with an auxiliary gas (24), to the exhaust gas (18). Subsequently, a catalytic reaction is performed in which, as starting products, carbon dioxide and/or carbon monoxide and hydrogen are converted into methane and water. The methane is separated off from the product of the catalytic reaction and is subsequently split into carbon and hydrogen, wherein the carbon takes solid form. The split-off carbon is collected and disposed of.
