SYSTEM AND METHOD FOR CAPTURING CARBON DIOXIDE FROM SHIFTED SYNGAS
First Claim
1. A system for capturing carbon dioxide from a shifted syngas, the system comprising:
- a solid sorbent configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature;
an absorption chamber configured to receive the shifted syngas at the first temperature; and
a regeneration chamber separate from the absorption chamber, the regeneration chamber being maintained at the second temperature,wherein the solid sorbent is cycled between the absorption chamber and the regeneration chamber such that carbon dioxide from the shifted syngas is absorbed within the absorption chamber to produce a decarbonized fuel gas and released within the regeneration chamber to produce a carbon dioxide stream.

Abstract
A system for capturing carbon dioxide from a shifted syngas is disclosed. The system may generally include a solid sorbent configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature. In addition, the system may include an absorption chamber configured to receive the shifted syngas at the first temperature and a regeneration chamber separate from the absorption chamber. The regeneration chamber may be maintained at the second temperature. The solid sorbent may be cycled between the absorption chamber and the regeneration chamber such that carbon dioxide from the shifted syngas is absorbed within the absorption chamber to produce a decarbonized fuel gas and released within the regeneration chamber to produce a carbon dioxide stream.

7. A power plant comprising:
-
a gasifier configured to produce a raw syngas; a shift reactor downstream of the gasifier, the shift reactor configured to convert the raw syngas into a shifted syngas including hydrogen and carbon dioxide; and a carbon dioxide capture system downstream of the shift reactor, the carbon dioxide capture system comprising; a solid sorbent configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature; an absorption chamber configured to receive the shifted syngas at the first temperature; and a regeneration chamber separate from the absorption chamber, the regeneration chamber being maintained at the second temperature, wherein the solid sorbent is cycled between the absorption chamber and the regeneration chamber such that carbon dioxide from the shifted syngas is absorbed within the absorption chamber to produce a decarbonized fuel gas and released within the regeneration chamber to produce a carbon dioxide stream. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for capturing carbon dioxide from a shifted syngas, the method comprising:
-
cycling a solid sorbent between an absorption chamber and a regeneration chamber, the solid sorbent being configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature; supplying shifted syngas into the absorption chamber at the first temperature such that the solid sorbent absorbs carbon dioxide from the shifted syngas as the solid sorbent is cycled through the absorption chamber to produce a decarbonized fuel gas; and heating the solid sorbent to the second temperature as the solid sorbent is cycled through the regeneration chamber such that the solid sorbent releases the carbon dioxide to produce a carbon dioxide stream. - View Dependent Claims (19, 20)
