On the relevant role of solids residence time on their CO2 capture performance in the Calcium Looping technology
(Pergamon Press, 2016)
The multicycle CO capture performance of CaO derived from natural limestone and dolomite has been investigated by means of thermogravimetry under realistic Calcium-Looping conditions, which necessarily involve high CO ...
