摘　　要：应用流化状态下的聚丙烯腈基活性碳纤维(PAN-ACF)对模拟的工业烟气中的SO2进行吸附脱除实验,通过改变烟气流量、烟气温度、烟气中水蒸气的体积分数及SO2的质量浓度、ACF的循环比及新加入ACF的质量流量,研究了流化状态下ACF脱除SO2效率的影响因素与变化规律.结果表明:PAN-ACF具有良好的脱硫性能,其脱硫效率随着烟气流量的增大、烟气温度的升高和SO2质量浓度的增高而降低,随着烟气中水蒸气体积分数的增高先增高后降低,随着ACF循环比与新加入ACF的质量流量的增大而增高.Adsorption and removal tests of SO2 in simulated industrial flue gas were done with polyacrylonitrile activated carbon fiber （PAN-ACF） in the fluidized state： Some influencing factors such as the flux and temperature of flue gas, mass concentration of SO2 and volume fraction of vapor in flue gas, recycle ratio of ACF, and mass flux of new ACF on the desulfuration efficiency of PAN-ACF were investigated. The results show that PAN-ACF has a better desulfurization performance. Its desulfuration efficiency decreases with increasing the flux and temperature of flue gas and the mass concentration of SO2, increases first and decreases later with increasing the volume fraction of vapor in flue gas, and increases with increasing the recycle ratio of ACF and the mass flux of new ACF.
