摘要:
为了研究在常温下活性炭材料孔径结构及材料形态对SO2吸附性能的影响,以5种不同孔径结构的沥青基活性炭纤维及活性炭颗粒为材料,通过吸附动力学模型的拟合,考查了活性炭孔径结构及材料形态与SO2吸附速率的关系.结果表明:较小的微孔径结构更有利于SO2的吸附;不同孔径结构的活性炭材料对SO2的吸附均符合Bangham动力学过程,活性炭纤维的吸附速率随孔径的增大而增大;活性炭颗粒因其形态结构的差异,吸附速度较活性炭纤维慢,吸附效
Abstract:
Five pitch-based activated carbon fibers with different pore structure and activated carbon particles were used for SO2 adsorption at room temperature. The effects of activated carbon pore structure and material morphology were investigated, and their impacts on the rate of adsorption were studied by adsorption kinetics as well. The results showed that, the smaller micropore structure is more conducive to its adsorption. The SO2 adsorption process of the activated carbon material can be described by Bangham kinetic equation, and the adsorption rate of activated carbon fibers increases with specific surface area and pore size. The adsorption rates of GAC are slower than ACF, and the SO2 adsorption properties of GAC are worse than ACF due to the different morphology.
