Abstract

The study investigated the potential of microwave energy in the synthesis of ZSM-5 zeolite with a reduced Na+ content for catalytic biomass pyrolysis, aiming to improve energy efficiency (by decreasing crystallization time) while preserving the morphology, textural parameters, and catalytic characteristics of the material. The subject of the study was a high-silica ZSM-5 zeolite with a SiO2/Al2O3 ratio of 50. The research focused on the physicochemical features arising during microwave treatment of the initial reaction mixture and the subsequent hydrothermal crystallization. Using X-ray diffraction and IR spectroscopy, the optimal duration of microwave exposure and the following crystallization phase was identified, ensuring the retention of at least 80% crystalline content. The results obtained are of both fundamental interest and practical value for the optimization of existing industrial technologies.
