The objective of this work is studied in particular the synthesis of MFI-type material microporous as catalysts incorporated with the zirconium. The [Zr] ZSM-5 was synthesized in succession without organic template by a hydrothermal process. X-ray diffraction (XRD) confirmed the ZSM-5 crystal phase. Fourier Transform Infrared (FTIR) analysis showed a band at 962 cm-1, probably because Si-0-Zr links, in addition to other characteristic bands of MFI structure of [Zr] -ZSM-5. In this aim, we tested different types of treatments without and in the presence of a catalyst for the oxidation of sulfur heterocyclic, 2- Mercaptobenzimidazole with H2O2 as oxidant.
