HIGH PERFORMANCE CO2/H2O DISPLACEMENT DESORPTION SORBENTS AND METHODS OF MAKING SAME

摘要

The disclosure generally relates to CCS sorbents, particularly for CO₂/H₂O displacement desorption process. The sorbents include an aluminum oxide support that includes alkali metal salts within the support, in the form of pseudo alkali aluminate. The sorbents also include alkali metal salt impregnated on the support. The sorbents demonstrate improved CO₂ loadings and better H₂O/CO₂ ratios, as well as improved stability. Compositions and methods of making are disclosed.
