Abstract: A method for manufacturing a hydrocarbon compound from carbon dioxide, said method including: (a) a step of preparing an absorption-conversion catalyst that includes an oxide carrier, a first component supported on the oxide carrier and including at least one type of metal selected from the group consisting of alkali metals and alkaline earth metals, and a second component supported on the oxide carrier and including at least one type of metal selected from the group consisting of Ni, Fe, Co, Cu, and Ru; (b) a step of bringing the absorption-conversion catalyst and a carbon dioxide-including gas into contact under higher pressure than atmospheric pressure, and causing the carbon dioxide to be stored in the absorption-conversion catalyst; and (c) a step of bringing the absorption-conversion catalyst that has the carbon dioxide stored therein and a reducing gas into contact under higher pressure than atmospheric pressure, and obtaining the hydrocarbon compound.
