Methods and systems for producing a synthetic fuel are disclosed. In some embodiments, the methods and systems include the following: thermally reforming methane and carbon dioxide to generate a syngas including a first quantity of carbon monoxide and a first quantity of hydrogen; oxidizing the quantity of first carbon monoxide with a metal to produce metal oxide and carbon thereby separating oxygen from the carbon monoxide; gasifying the carbon using steam to produce a second quantity of carbon monoxide and a second quantity of hydrogen; reacting the metal oxide with methane to produce metal oxide, carbon dioxide, and a third quantity of hydrogen; and synthesizing the first quantity of carbon monoxide, the first quantity of hydrogen, the second quantity of hydrogen, and the third quantity of hydrogen to form the synthetic fuel.

Methods and systems for producing synthetic fuel

The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (CO), particularly from the air. The COextraction methods and systems involve the use of chemical processes. Methods are also described for extracting and/or capturing COvia exposing air containing carbon dioxide to a solution comprising a base&#x2014;resulting in a basic solution which absorbs carbon dioxide and produces a carbonate solution. The solution is causticized and the temperature is increased to release carbon dioxide, followed by hydration of solid components to regenerate the base.

Systems and methods for extraction of carbon dioxide from air

The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (CO), particularly from the air. The COextraction methods and systems involve the use of chemical processes, mineral sequestration, and solid and liquid sorbents. Methods are also described for extracting and/or capturing COvia condensation on solid surfaces at low temperature.

Carbon dioxide capture and mitigation of carbon dioxide emissions

The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (C0), particularly from the air. The COextraction methods and systems involve the use of chemical processes. Methods are also described for extracting and/or capturing COvia exposing air containing carbon dioxide to a solution comprising a base&#x2014;resulting in a basic solution which absorbs carbon dioxide and produces a carbonate solution. The solution is causticized and the temperature is increased to release carbon dioxide, followed by hydration of solid components to regenerate the base.
