Effect of heat pretreatment/recarbonation in the Ca-looping process at realistic calcination conditions
(American Chemical Society, 2014)
Even though an increasing number of pilot-scale plants are demonstrating the potential efficiency of the Ca-looping technology to capture CO2 at a commercial level, a still standing matter of concern is the loss of carbonation ...
