| 中文摘要 | 研究了CuO/γ-Al2O3脱硫剂脱除烟气中SO2的反应动力学。采用浸渍法制备了CuO/(γ-Al2O3)为0.12g/g脱硫剂,X-射线衍射(XRD)表明CuO呈亚单层状态分布。0.12gCuO/g(γ-Al2O3)脱硫剂硫化反应的等压吸附表明,在100～300℃、300～550℃、550～800℃范围内,SO2的吸附性质分别为物理吸附、化学吸附、化学脱附。针对化学吸附过程,提出了Langmuir反应动力学模型。计算得到SO2的反应级数为1级,活化能Ea为19.98kJ/moL,指前因子K0为9.97×10-5s-1.Pa-1。模型检验显示Langmuir反应动力学模型可以很好地描述CuO/(γ-Al2O3)为0.12g/g脱硫剂硫化过程中CuO与SO2的反应。; Kinetics of sulfation of CuO/γ-Al_2O_3 desulfurizer was studied.A desulfurizer of 0.12 g CuO/g(γ-Al_2O_3) was prepared by impregnation and characterized by X-ray diffraction which showed that the dispersion of CuO supported on γ-Al_2O_3 was submonolayer.Isobar showed that physical adsorption,chemical adsorption,and chemical desorption occurred during 100～300℃,300～550℃,and 550～800℃ respectively.Langmuir reaction kinetic model was proposed to describe chemical adsorption of SO_2.Reaction order with respect to SO_2 was first order,and activation energy was 19.98 kJ/mol,pre-exponential was 9.97×10~ -5 s~ -1 ·Pa~ -1 .Correlation coefficients showed that the Langmuir reaction kinetic model described experimental results well.; 国家自然科学基金(90210003); 北京市自然科学基金(2012010) |
