摘要
分别采用等体积浸渍法和离子交换法制备一系列AgX吸附剂。通过化学吸附仪(CO-TPR)、傅里叶变换红外光谱仪(FT-IR)、固体紫外可见漫反射光谱仪、X射线衍射仪(XRD)和X射线荧光光谱仪(XRF)等对吸附剂进行了表征;以模拟油品为原料,在小型固定床吸附与脱附器(200mL)上考察了吸附剂的烷烃/烯烃分离性能。结果显示,与离子交换方法相比,浸渍法制备AgX吸附剂的烯烃分离性能更好,烷烃/烯烃分离度最高且不存在拖尾现象。与新鲜剂相比,再生后吸附剂的烯烃分离效果没有明显下降。
A series of AgX adsorbents were prepared by equal volume impregnation and ion exchange,respectively.The ad- sorbent was characterized by chemical adsorption instrument(CO-TPR),Fourier transform infrared spectroscopy(FT-IR),solid ultraviolet visible(UV) diffuse reflectance spectrometer,X-ray diffractometer(XRD) and X-ray fluorescence spectro- meter(XRF).The alkane/olefin separation performance of the adsorbent was investigated on a small fixed bed adsorption and desorption reactor(200 mL) using simulated oil as the raw material.The results showed that compared with the ion exchange method,the olefin separation performance of the AgX adsorbent prepared by the impregnation method was better,the alkane/olefin separation degree was the highest and there was no tailing phenomenon.The olefin separation effect of the regenerated adsorbent was not significantly reduced as compared with the fresh adsorbent.
