Popis: Nanostructured ZnAPSO-34 catalyst was successfully synthesized in stirring and static conditions via hydrothermal method. Effect of difference rpm of stirring on the crystallinity, morphology, surface area and catalytic performance of ZnAPSO-34 were investigated. Synthesized catalysts were characterized by various methods such as XRD, FESEM, BET and FTIR techniques. By increasing of stirring rpm, relative crystallinity initially increased and then reduced. By using of hydrothermal method under stirred conditions, nanoparticles of ZnAPSO-34 with narrow particle size distribution were produced. The synthesized catalysts were applied in methanol to ethylene and propylene process and effect of synthesis conditions on catalytic performance was investigated. The synthesized sample at 300 rpm exhibited the longer lifetime than the other samples. Moreover, methane formation for this sample was low.
