ZnO/CNTs复合材料吸附脱除H2S的性能研究

Study on adsorption and removal of H_2S by ZnO/CNTs composites

采用热分解法制备Zn O/CNTs复合材料,通过傅立叶变换红外光谱(FT-IR)、X射线衍射(XRD)、透射电镜(TEM)、扫描电镜(SEM)和N_2吸脱附测试分别表征样品的结构、形貌特征及比表面积,并使用固定床反应器测试其吸附脱硫性能.结果表明,制备的Zn O/CNTs具有吸附脱除H_2S能力物质为Zn O,当Zn O的负载量为0.5%时,穿透时间可达到185 min,穿透硫容最高.

ZnO/ carbon nano-tubes （CNTs） composites were prepared by thermal decomposition meth-od. The structure, morphology and specific surface area of the samples were characterized by Fouriertransform infrared spectroscopy （FT-IR）, X-ray diffraction （XRD）, transmission electron microscopy（TEM）, scanning electron microscopy （ SEM） and N2 desorption, and the adsorption desulfurizationperformance was measured using a fixed bed reactor. The results show that the prepared ZnO/ CNTs hasthe ability to remove H2S by ZnO. When the loading of ZnO was 0.5%, the penetration time was up to185 min with the highest sulfur mass content.
