The proximate and ash analyses of the paper sludge and calcined limestone (Kangwon Province, Korea) used as a reference material are shown in Table 1.
0 as in the case of calcined limestone particles (Kang et al.
Sulphation conversion of the ash is found to be higher than that of the calcined limestone having low (25-45%) reactivity (Kang et al.
The effect of particle size of the ashes A, B and the calcined limestone on sulphation conversions at 900 [degrees]C at [SO.
Scanning electron microscopy (SEM) analyses were performed to characterize the surface and pore properties of the ashes and the calcined limestone before and after sulphation as shown in Figure 8.
5-2 times higher than that of the calcined limestone.
