%X In this work we presented a study over the generation of mesoporosity in ZSM-5 zeolites with ratio Si/Al of 10 and 35 synthesized in inorganic medium. A mesoporous phase with hexagonal arrangement that coexists with the zeolite ZSM-5 remnant, was obtained after alkaline treatment of zeolite followed by hydrothermal treatment in the presence of CTAB surfactant micelles. The acidity and catalytic activity of the zeolite ZSM-5 with higher relation Si/Al were kept after the treatment, whereas a notable decrease of these properties was obtained for the zeolite with minor relation Si/Al
