Thermogravimetric analysis (TGA) was used to study the adsorption phenomena of CO2 and H2O on a hydrotalcite-based adsorbent to be used for sorption-enhanced Water-Gas-Shift (SEWGS). The adsorption of CO2 and H2O and the interaction between the two can be described when considering the presence of at least three different sites (2 for CO2 and 1 for H2O) participating in the adsorption phenomena at elevated temperatures. The experiments confirm that the regeneration conditions are crucial for activating more sites for CO2 adsorption and are therefore the limiting factor for the cyclic working capacity of the adsorbent.
