The effects of nano-TiO2 dosage, Ca/S and temperature on CaO desulfurization and coal combustion were studied. The products were characterized by SEM and IR analysis. The catalysis mechanisms of nano-TiO2 were discussed. The results show that desulfurization efficiency was 87.7% when nano-TiO2 dosage is 6%, Ca/S 2, temperature 850degC; it was 16.8% higher than that without addition. The ignition temperature,...
