Effect of Powder Activated Carbon Circulation Rate on SO2 Adsorption
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.
