AgHY分子筛的吸附脱硫性能OACSTPCD
Performance of Adsorptive Desulfurization over Modified AgHY Zeolites
以等体积浸渍法制备不同负载量的AgHY分子筛,利用物理吸附仪和X射线衍射(XRD)技术对分子筛吸附剂进行表征.BET结果表明改性分子筛的比表面积和孔容随Ag的负载量的增加而降低,XRD图谱的变化表明,银的负载仅降低了衍射峰强度,而对HY的骨架结构没有影响,并且也没有Ag2O的特征峰出现.在静态吸附条件下考察了改性AgHY分子筛吸附剂对二苯并噻吩(DBT)的脱除性能.结果表明,Ag改性的HY分子筛具有较好的吸附脱硫性能和再生性能.应用Ag负载量为1…查看全部>>
The AgHY zeolite absorbents with different Ag loadings are prepared by incipient-wetness impregna tion. The physical adsorption analyzer and the X-ray diffraction are employed to characterize these absorbents. The BET results show that the surface areas and pore volumes of AgHY zeolites decrease with an increase in Ag loading. The introduction of Ag lowers the intensities of the XRD peaks of HY zeolite without changing bas ic framework. None of Ag2O peaks a…查看全部>>
