“…Wu et al 268 found that adding Ca(OH) 2 to K 2 CO 3 / Al 2 O 3 can not only increase the CO 2 capture capacity, but also improve its SO 2 resistance. Derevschikov et al 269 reported that Y 2 O 3 could be used as a potential support instead of Al 2 O 3 for dispersing K 2 CO 3 .…”

“…The CO2 desorption rate depends on the temperature, CO2 concentration in the gas phase and internal diffusion rate inside the pellets. It is well known that the process can be performed in the kinetic regime by applying very thin sorbent layers onto structured supports [44]. Recently, the application of metal wires, gauzes and foams as support for reforming catalysts and sorbents is also considered [45].…”

“…38 Primer studies on capturing atmospheric CO 2 using K 2 CO 3 supported over alumina or yttrium oxide showed that in order to keep a stable adsorption capacity the regeneration must be carried at 150 °C. 20,21 …”
