Abstract
A method of removing carbon dioxide from a gas can include providing a gaseous feed stream including a carbon dioxide gas and adsorbing the carbon dioxide gas with a porous carbon sorbent. The method can further include de-adsorbing the carbon dioxide and combining the carbon dioxide with a substantially pure hydrogen gas to produce at least one of methane and methanol. The adsorbing and de-adsorbing of the carbon dioxide gas can be conducted by an electric swing adsorption.
Claims19
A carbon dioxide separation system, comprising:
- a gaseous stream including carbon dioxide;
- an activated carbon filter comprising nanopores, wherein the gaseous stream including carbon dioxide is configured to flow through at least a portion of the activated carbon filter, the activated carbon filter being configured to separate the gaseous stream into a carbon dioxide-rich stream and a carbon dioxide-depleted stream;
- and
- an adsorption system configured to separate the carbon dioxide-rich stream.
A method of producing carbon dioxide, comprising:
- passing a carbon dioxide-containing gas through a graphene based membrane;
- preparing an apparatus comprising a porous dielectric adsorbent material in between and in electrical communication with a first electrical conductor and a second electrical conductor;
- applying an electric field across the porous dielectric adsorbent material;
- passing the carbon dioxide-containing gas into the porous dielectric adsorbent material, wherein the carbon dioxide couples to the first electrical conductor and the second electrical conductor;
- removing the electric field and releasing the carbon dioxide;
- and
- capturing the carbon dioxide.
A method of removing carbon dioxide from a gas, comprising:
- providing a gaseous feed stream including a carbon dioxide gas;
- adsorbing the carbon dioxide gas with a porous carbon sorbent comprising a nanoporous single-layer graphene membrane;
- and
- de-adsorbing the carbon dioxide.
