Capture of carbon dioxide by hybrid sorption |
| 摘要 |
A composition, process and system for capturing carbon dioxide from a combustion gas stream. The composition has a particulate porous support medium that has a high volume of pores, an alkaline component distributed within the pores and on the surface of the support medium, and water adsorbed on the alkaline component, wherein the proportion of water in the composition is between about 5% and about 35% by weight of the composition. The process and system contemplates contacting the sorbent and the flowing gas stream together at a temperature and for a time such that some water remains adsorbed in the alkaline component when the contact of the sorbent with the flowing gas ceases. |

1. A process for capturing carbon dioxide from a flowing gas stream, comprising:
i) providing a carbon dioxide sorbent composition comprising a particulate porous support medium that has a high volume of pores, an alkaline component distributed within the pores and on the surface of the support medium, and water, wherein the proportion of water in the sorbent composition is between about 5% and about 35% by weight of the sorbent and the weight percent of the active alkaline component in the sorbent composition is at least 20%; and ii) contacting the sorbent and the flowing gas stream together at a temperature and for a time such that some or all of the absorbed water is evaporated from the sorbent when the contact of the sorbent with the flowing gas ceases. |
