摘要：

Five commerical calcium hydroxides were tested in a fixed-bed reactor for SO2 removal at bag-filter conditions. Small amounts of different additives (fly ash, NaOH, NaCl and CaCl2) were added to the commerical Ca(OH)2 which showed the greatest reactivity respect to SO2 (by a drying process). Fly ash performance was negative whereas the rest of additives enhanced the desulfurization power of the Ca(OH)2, specially NaOH (due to its basic and deliquescent character) and CaCl2 (by its delilquescence). CaCl2 has been the best additive tested at the used experimental conditions.
