Abstract
Rates of sorption of SO2 from synthetic flue gas by 14 metal oxides were determined. These oxides had been selected for their potential applicability to processes for removing SO2 from flue gas using thermal regeneration of sorbent. Measurements were performed using thermogravimetric analysis, and rates were fitted to semi‐empirical expressions; CeO2, Co3O4, Cr2O3, CuO, Fe2O3, and NiO displayed measurable rates in the range 200° to 500°C, and were converted to sulphates. Rates were immeasurably small at 25° to 800°C for Al2O3, Sb2O5, SnO2, TiO2, V2O5, WO3, ZnO, and ZrO2, CuO and CeO2 showed the highest ratesKeywords
