Abstract:
|
Climate change is one of the greatest challenges issues facing the world this century. Cement industry represents
around 5% of the total anthropogenic carbon dioxide emissions worldwide. The carbonate looping process seems a
promising CO2 capture technology for cement industry as the sub-product can be used in the cement manufacturing
process. It is based in the reversible reaction between CaO and CaCO3 to produce a stream with high CO2
concentration. One of the main drawbacks of this technology is the loss of adsorption capacity of the sorbent.
Limestone samples have been calcined under different conditions in a tubular reactor and analyzed in the BET
apparatus. Also, limestone was tested in a thermogravimetric analyzer (TGA). All experiments were performed at
realistic carbonation-calcination conditions unlike most of the experimental work presented in the literature. The
application of realistic conditions accelerates and increases sintering as well as the CO2 carrying capacity of the
sorbent. |
