Effect of approach to adiabatic saturation temperature on flue gas desulfurization by PAN-ACF

The polyacrylonitrile-based activated carbon fiber(PAN-ACF) is one kind of newer carbon material.Adsorption and removal experiments of SO₂ in simulated flue gas by PAN-ACF were carried out.The influences of approach to adiabatic saturation temperature(AAST) on the desulfurization efficiency were investigated by changing the flue gas temperature and the volume fraction of vapor,respectively.The results show that PAN-ACF has effective desulfurization performance,AAST is the important influencing factor on the desulfurization efficiency,and the desulfurization efficiency increases at first and then decreases with increasing AAST.By comparison,the desulfurization efficiency of PAN-ACF at the same AAST by changing the flue gas temperature differs from that by changing the volume fraction of vapor,and their changing tendencies with AAST are also different.
