The potential of giant ZSM-5 zeolites synthesized in fluoride medium in the conversion of methanol into propylene led us to investigate the replacement of harmful hydrofluoric acid by non-toxic H3PO4. P-ZSM-5 zeolites were synthesized and thoroughly characterized by XRD, SEM, FT-IR, TPD propylamine, H/D isotope exchange and XRF analyses. The catalytic performance of these acid catalysts was evaluated in the methanol-to-olefins reaction at 673K. The presence of phosphorous in the zeolite after calcination was ascertained and induced high ethylene selectivity (up to 33%) and improved catalyst stability with respect to fluoride-mediated zeolites.
