Hierarchical ZSM-5 Zeolite Synthesized Only with Simple Organic Templates

Hierarchical zeolites have attracted more and attention due to their excellent diffusion mass transfer performance. However, synthesis of most hierarchical requires long-chain organic templates, which could increase preparation cost. Here, ZSM-5 were successfully prepared with simple templates (triethylenetetramine) in a rotating oven. Besides structure, the crystal size also decreased when they synthesized under dynamic hydrothermal conditions. The samples analyzed using various physicochemical characterizations, such as X-ray diffraction (XRD), fluorescence (XRF), scanning electron microscopy (SEM), Fourier transform infrared spectra (FT-IR), temperature-programmed desorption ammonia (NH3-TPD) N2 adsorption–desorption. oven presented better catalytic activity stability iso-butane cracking reaction than those conventional static
