Abstract

The zeolites HZSM5 and HMOR were synthesized and their behavior analyzed during the conversion from methanol to propylene (MTP). These zeolites were studied with XRD, SEM, NH3-TPD, nitrogen adsorption at 77 K and adsorption microcalorimetry. It was established that acidity influences the conversion of methanol to propylene. The development of mesopores in HMOR allowed the process to be more selective for MTP process. The role that acid and basic sites and the ratio Si/Al play in the conversion process was determined.
