摘要
用浸渍法制备了不同MoO3担载量的Mo/ZSM-5分子筛催化剂,并利用XRD、BET和NH3-TPD及Py-IR等分析方法对催化剂进行表征.结果表明,担载了Mo后的Mo/ZSM-5分子筛在773K温度焙烧下,仍保持了ZSM-5分子筛骨架的完整性,Mo物种已进入分子筛孔道.随着Mo担载量的增加,Mo/ZSM-5分子筛的比表面和总酸量均下降.
The Mo/ZSM-5 zeolites＇ catalysts with different MoO3 loading were prepared by impregnation method. The catalysts were characterized by XRD,BET,NH3-TPD and Py-IR method. The results showed that the frameworks of the ZSM-5 zeolites were retained and Mo species were entered into the channels of ZSM-5 zeolites when the samples were calcined at 773 K. With increasing the amount of MoO3 loading, the surface area and total amount of acid in the Mo/ZSM-5 catalysts decreases.
