研究了HZSM－5、ZnHZSM－5和ZnNaZSM－5上的羟基振动光谱和一氧化碳吸附的红外光谱，以及丙烷的芳构化反应．红外光谱中发现表征强B酸的3610cm－1羟基振动峰相对强度由于锌离子的引入和浸渍氢氧化钠而减小，说明了锌离子和钠离子均进入了分子筛的阳离子位；一氧化碳在锌离子上的吸附峰位在2232cm－1，说明进入阳离子位的锌离子是一种强L酸．反应结果表明，锌离子的引入大大地促进了丙烷的转化和芳烃选择性的提高；在一定范围内，随浸渍氢氧化钠量的增加，丙烷转化率下降，而丙烯的选择性和产率增加，说明了锌组份直接参与了丙烷的脱氢过程．Zn－L酸是丙烷活化脱氢的中心，丙烷在该中心上异裂活化直接脱氢．
The hydroxyl vibrational spectra and carbon monoxide adsorption spectra of HZSM-5, ZnHZSM-5 and ZnNaZSM-5 were studied, as well as the aromatization of propane. It was found that the relative intensity of 3610cm-1 hydroxyl vibration peak of strong B acid in IR spectra decreased due to the introduction of zinc ions and the impregnation of sodium hydroxide, indicating that zinc ions and sodium ions all entered the cation sites of the molecular sieve. The adsorption peak on the 2232cm-1, indicating that the zinc ion into the cationic position is a strong L acid. The reaction results showed that the introduction of zinc ion greatly promoted the conversion of propane and the selectivity of aromatics; within a certain range, with the increase of the amount of sodium hydroxide impregnated, the conversion of propane decreased while the selectivity and yield of propylene increased , Indicating that the zinc component is directly involved in the dehydrogenation of propane. Zn-L acid is the center of propane activation dehydrogenation, propane in the center cracking directly activated dehydrogenation.
