Carbonatation and Decarbonatation Kinetics in the La2O3-La2O2CO3 System under CO2 Gas Flows
Figure 5
Evolution of versus 103/T of initial La2O3 sample during its carbonatation and decarbonatation, in the temperature range 300 to C, under a constant CO2 gas flow: (a) starting step of carbonatation between 450 and C with two conduction regimes; (b) decarbonatation step above C.
