Abstract
A carbon dioxide collection and utilization system including: a regeneration unit that produces, from a solid material in or on which carbon dioxide is absorbed or adsorbed, a gas containing the carbon dioxide, and regenerates the solid material; a reactor into which the gas containing the carbon dioxide produced in the regeneration unit and hydrogen are introduced and which produces steam and at least one selected from the group consisting of synthetic fuel, methane, and methanol; and a steam introduction line that introduces at least part of the steam produced in the reactor, into the regeneration unit.
Claims7
A carbon dioxide collection and utilization system, comprising:
- a regeneration unit that produces, from a solid material in or on which carbon dioxide is absorbed or adsorbed, a gas containing the carbon dioxide, and regenerates the solid material;
- a reactor into which the gas containing the carbon dioxide produced in the regeneration unit and hydrogen are introduced and which produces steam and at least one selected from the group consisting of synthetic fuel, methane, and methanol;
- and
- a steam introduction line that introduces at least part of the steam produced in the reactor, into the regeneration unit.
A carbon dioxide collection and utilization method, comprising:
- a preparation step of preparing a solid material in or on which carbon dioxide is absorbed or adsorbed,
- a regeneration step of producing from the solid material in or on which carbon dioxide is absorbed or adsorbed, a gas containing the carbon dioxide and regenerating the solid material;
- and
- a reaction step of allowing the gas containing the carbon dioxide to react with hydrogen, to produce steam and at least one selected from the group consisting of synthetic fuel, methane, and methanol, wherein
- the regeneration step includes bringing at least part of the steam into contact with the solid material in or on which carbon dioxide is absorbed or adsorbed.
