Effect of Powder Activated Carbon Circulation Rate on SO₂ Adsorption

Abstract:

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.
