| 英文摘要 | The accessibility and acidity of HZSM-35 zeolite were studied by high-resolution solid-state MAS NMR spectroscopy after adsorption of deuterated pyridine or trimethylphosphine as probe molecules. The results showed that the probe molecules could enter both the ten-membered ring (10-MR) channels and eight-membered ring (8-MR) cavities. However, the diffusion into the 8-MR cavities was very slow and it took a long time to reach the adsorption equilibrium at 300 degrees C. After adsorption of deuterated pyridine, H-1 MAS NMR spectra showed that there were two types of Bronsted acidic sites with different strength in both the 10-MR channels and 8-MR cavities. After adsorption of trimethylphosphine, the P-31 MAS NMR spectra indicated that there were Lewis acidic sites in HZSM-35 zeolite, but their strength and amount were less than the Bronsted acidic sites. |
