英文摘要 | Zsm-22 zeolite with different crystal lengths was prepared using a modified hydrothermal method. rotation speed, si/al molar ratio and co-solvent have important effects on the crystal size of zsm-22. the nanosized zeolite samples were characterized by x-ray diffraction, x-ray fluorescence, nitrogen adsorption, scanning electron microscopy, temperature-programmed desorption of ammonia and solid state nuclear magnetic resonance. the catalytic performance of nanosized zsm-22 was tested using the conversion of methanol. compared to conventional zsm-22, the nanosized zsm-22 zeolite exhibited superior selectivity to ethylene and aromatics and lower selectivity to propylene. stability against deactivation was clearly shown by the nanosized zsm-22 zeolite. a higher external surface area and smaller particle size make this nanosized zsm-22 zeolite attractive for catalytic applications.
