Kinetics of the carbonation reaction of an SrO-Al2O3 composite for thermochemical energy storage

• The carbonation kinetics of a SrO-Al 2 O 3 composite has been investigated for TCES-CSP. • SrO has been stabilized using Al 2 O 3 as a sintering/agglomeration inhibitor. • The fast carbonation stage is well described by the contracting volume model. • The slow carbonation stage is well described by the Jander’s model. • Activation energy of the SrO-Al 2 O 3 carbonation reaction at the 900–1000 °C was estimated as 52 kJ/mol. In framework of the...
