Abstract	CO2 capture from combustion processes faces several challenges including high energy penalty, low CO2 partial pressure, high flow rates and presence of water vapours. Absorption of CO2 at high temperature is recently attracting increasingly attention. Alkali metal based sorbents present clear advantages compared to other high temperature sorbents, such as high CO2 capture capacity, lower regeneration temperatures (<750°C) and excellent stability. In this work, Na/Li-silicates prepared by mixing Na/Li carbonates with fly ash (FA) in various molar ratios were evaluated for their capacity to chemisorb CO2 at 500–700°C and in presence of H2O (2–12vol%), diluted CO2 (14vol%) and CO2 sorption promoters.
