| 摘 要： | 运用N2保护下的离子交换法制备Fe-SAPO-44分子筛催化剂,通过X射线粉末衍射(XRD)、N2吸附-脱附、电感耦合等离子体发射光谱仪(ICP-AES)、扫描电子显微镜(SEM)和氨气程序升温脱附(NH3-TPD)等研究Fe-SAPO-44催化剂的物化性质。对Fe-SAPO-44催化剂进行脱硝活性测试,考察其抗水热老化性能。结果表明,制备的Fe-SAPO-44催化剂的脱硝活性良好,并具有较好的抗水热老化能力。

| Abstract: | Fe-SAPO-44 zeolite was synthesized by ion exchange in N2 atmosphere and characterized by X-ray powder diffraction(XRD),N2 adsorption-desorption,inductively coupled plasma-atomic emission spectrometer(ICP-AES),scanning electron microscopy(SEM),NH3 temperature programmed desorption(NH3-TPD).Fe-SAPO-44 catalyst was tested in selectivity reduction of NO with NH3(NH3-SCR) to study its hydrothemal aging resistance.The results showed that Fe-SAPO-44 had good NH3-SCR activity and resistance to hydrothemal aging. |
