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, to the exhaust gas. 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. Thesplit-off carbon is collected and treated. 本发明涉及一种从废气(18)中分离和固定二氧化碳和/或一氧化碳的方法。在该方法中，通过附加气体向废气中添加相应量的氢气或二氧化碳和/或可能的一氧化碳，以确保二氧化碳与氢气和/或一氧化碳与氢气的化学计量比适用于甲烷化反应。随后，进行催化反应，其中作为起始产物的二氧化碳和/或一氧化碳和氢气转化为甲烷和水。将甲烷与催化反应的产物分离，并裂解成碳和氢。收集并处理分离的
