| Abstract: | The sewage sludge was used to produce adsorbent by controlling the pyrolytic and chemical conditions.Using the adsorbent derived from sewage sludge to adsorb the low concentration SO2 in fixed bed system, the effects of the metallic derivatives on characteristics of the adsorbent were investigated at different compositions of the gaseous mixtures. The results show that when the mass fraction of vanadium reaches 0.5% and the mass fraction of iron, calcium, copper, nickel reach approximately 0.9%, under the condition that the adsorption mixture contains 0.12%SO2, 3%O2 and 10% water vapor, the maximum adsorption capacity of SO2 can be obtained to be 128, 109,90, 82, 78 mg@ g-1 , respectively. So the metallic derivatives fixed onto adsorbent derived from sewage sludge especially vanadium have great effects on of the sorption characteristics of the adsorbent with respect to SO2. |
