| 摘 要： | 以不同氧化物为载体, 通过挤条成型法制备了 Mo/ZSM-5 催化剂, 考察了其催化甲烷无氧芳构化反应性能. 采用吸附吡啶红外光谱、氨程序升温脱附和氢程序升温还原等方法对催化剂进行了表征. 结果表明, ZnO 的添加使催化剂的强酸量减少, 强 B 酸比例降低, Mo 物种还原能力提高, 因而催化剂表现出较高的甲烷芳构化活性和较低的积炭选择性. |

| Abstract: | The Mo/ZSM-5 catalysts extruded with various oxides as supports were prepared. Fourier transform infrared spectroscopy of pyridine adsorption, NH3 temperature-programmed desorption, and H2 temperature-programmed reduction were employed to characterize the catalysts. Methane dehydroaromatization in the absence of oxygen over the catalysts was investigated in a fixed-bed reactor. The results showed that the catalyst extruded with ZnO presented the highest activity among all the catalysts tested. Methane conve... |
