Abstract

In the present work, HZSM-5 zeolite nanoparticles were prepared under hydrothermal conditions by using n-butylamine, tetrapropylammonium bromide, and n-butylamine-tetrapropylammonium bromide mixture as a template. The obtained examples were intently characterized via N2 adsorption–desorption, ammonia temperature-programmed desorption (NH3-TPD), X-ray diffraction, and transmission electron microscopy (TEM) techniques. The acquired outcomes showed that using the mixture of templates caused to increase in the mesoporosity of HZSM-5 zeolite. Also, the particle size of the synthesized zeolites was reduced by applying the mixture of templates. Next, the prepared zeolites were used as a catalyst in the methanol to propylene (MTP) synthesis, and their activity was evaluated. The results indicated that the catalyst prepared from the mixture of templates had the lowest deactivation rate in the MTP process. These outcomes appeared that there is a straight connection between the deactivation and acidic properties of catalysts.
