摘要
本文考察了流动态体系中,烟气主要组分(O_2和水蒸汽)的含量对SO_2在活性炭上吸附量的影响;研究了SO_2吸附动力学。结果表明,在一定空速和吸附温度下,烟气中O_2和水蒸汽含量分别为5％和8％(Ⅴ％)左右时,SO_2吸附量为最大。SO_2在活性炭上吸附动力学曲线很好地遵循Elovich方程;SO_2吸附活化能E_(?)~0为21.939×10~3J/mol以及Elovich参数,进而得出吸附活化能E_6,与吸附温度的关系。
Influence of the main component (O2 and water steam) m flue gas on the amount ot adsorption and the dynamics of adsorption of SO2 on active carbon catalysts were studied by flow method. It was found chat when the content of O2 is about 5% (V%) and the content of water steam is about 8%, adsorption amount of SO2 on the catalyst reached the maximum value. Adsorption dynamics ot SO2 almost exactly fit the law of Elovich, The apparent adsorption activation energy (E0 a), Elovich parameters and the relation between adsorption activation energy and temperature were hence obtained.
