Method of producing hydrocarbon and apparatus for producing hydrocarbon
A hydrocarbon is produced by applying mechanical energy to a metal body containing stainless steel by solid-solid contact so that a contact pressure per unit area is 30 kPa or more, in the presence of a gas containing carbon dioxide and a hydrogen source, thereby adding hydrogen to carbon dioxide. Further, a hydrocarbon is produced by providing a reaction vessel for applying mechanical energy to a metal body by solid-solid contact in the presence of a gas containing carbon dioxide and a hydrogen source, a gas introduction unit for introducing the gas containing carbon dioxide to the reaction vessel, a hydrogen source introduction unit for introducing the hydrogen source to the reaction vessel, and a gas discharge unit for discharging a gas containing the hydrocarbon produced in the reaction vessel, and adding hydrogen to the carbon dioxide in the reaction vessel.

a vessel for providing a space;
a first introduction unit for introducing a gas containing carbon dioxide to the space,
a second introduction unit for introducing a hydrogen source to the space; and
a discharge unit for discharging a gas containing hydrocarbon from the space,
wherein the vessel is configured so that mechanical energy is applied to a metal body in the space by a contact between the metal body and a hard body with a contact pressure per unit area of the metal body being 30 kPa or more.
