Physicochemical Properties of Mechanochemical Activated HZSM‑5 Zeolite for Thermocatalytic Pyrolysis of Polypropylene.

ABSTRACT: In this work, we explore a mechanochemical approach using ball milling to synthesize hierarchical HZSM-5 zeolites, eliminating the need for hydrothermal processing. The synthesis was conducted using dual organic templates, cetyltrimethylammonium bromide (CTMABr), and tetrapropylammonium bromide (TPABr), under varying conditions of milling time, rotational speed, and solvent presence. The aim was to investigate the structural evolution of ZSM-5 under mechanical activation while avoiding amorphization. Characterization techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and nitrogen physisorption revealed that even five minute of milling induced significant modifications in the chemical structure and morphology.
