Powder Activated Carbon

SO2 adsorption by powder activated carbon was investigated in a low temperature drop tube furnace. The effects of C/S mole ratio, adsorption temperature, SO2, O2 and H2O concentration on SO2 adsorption kinetics were studied. The results show that SO2 is quickly adsorbed on powder activated carbon in the initial stage and then SO2 adsorption capacity slow increases with time. The Bangham kinetic model can be used to predict SO2 adsorption in the low temperature drop tube furnace. SO2 removal efficiency increases and SO2 adsorption capacity decreases with C/S mole ratio increasing. SO2 removal efficiency and SO2 adsorption capacity both decrease with adsorption temperature increasing. SO2 removal efficiency decreases and SO2 adsorption capacity increases with SO2 inlet concentration increasing. The O2 and H2O from flue gas promote SO2 adsorption by powder activated carbon.

SO2 adsorption by powder activated carbon was investigated in a low temperature drop tube furnace experimental system. The effects of C/S mole ratio and activated carbon circulating ratio on SO2 adsorption was studied. The results show that SO2 is quickly adsorbed on the powder activated carbon in the initial stage and the amount of SO2 adsorbed increases with time. SO2 removal efficiency increases with increasing C/S mole ratio. Powder activated carbon recycling is important to enhance desulfurization efficiency, reduce the amount of adsorbents and improve the utilization of activated carbon. SO2 is removed effectively when the C/S mole ratio is 300 and the powder activated carbon circulating ratio is seven.
