Limestone calcination under calcium-looping conditions for CO2 capture and thermochemical energy storage in the presence of H2O: An in situ XRD analysis
(Royal Society of Chemistry, 2017)
This work reports an in situ XRD analysis of whether the calcination/carbonation behavior of natural limestone (CaCO3) is affected by the addition of H2O to the calciner at a very low concentration under relevant Calcium-Looping ...
