Oxidation of SO2 in a trickle bed reactor packed with activated carbon at low liquid flow rates
In this study, the oxidation of SO2 on activated carbon (AcC) by using distilled water and air was carried out in a laboratory scale trickle bed reactor (TBR). Distilled water and air containing 1.7 % (v/v) SO2 were fed co-currently downward through a fixed bed of AcC particles in a range of 1-7 cm(3)/s and 10-27 cm(3)/s respectively. H2SO3/H2SO4 solutions were the products obtained in the liquid phase. Steady-state experiments were performed in a column of 0.15 m packing height and 0.047 m column diameter at 20 degrees C and atmospheric pressure. Experimental reaction rates of this study were compared with those of other studies on the basis of plug flow model of Mata-Smith given in literature.
