Hydrophobic sorbents for CO2/H2O displacement desorption applications
Abstract
The disclosure generally relates to CCS sorbents, particularly for CO2/H2O displacement desorption process. The sorbent includes an aluminum oxide support and an alkali metal salt impregnated on the support, and a silicon modification of the sorbent to reduce water uptake by the sorbent and make it more hydrophobic. The silicon modification can be an organosilyl moiety added after the initial sorbent is complete, or a silica source added to the aluminum oxide structure, typically via impregnation. The sorbents demonstrate better H2O/CO2 ratios. Compositions and methods of making are disclosed.
