摘要

Superfine HZSM-5 zeolites were synthesized by different methods, and their catalytic performance for the coupling conversion of methanol and 1-butylene to propylene was investigated. In addition, these catalysts were characterized by XRD, SEM, N_2 isothermal adsorption-desorption, and NH3-TPD. Z5-A catalyst showed the highest reactivity among these catalysts and could keep good stability, due to its superfine particle size, large surface area and proper acidity.
