Overview

Evaluation of zsm-5 zeolites shows how acidity and crystal morphology affect catalytic processes in toluene alkylation.

Key Points

  • Catalyst activity peaks at 0.43 mmol NH3 g cat −1 and maintains around 25% efficiency for higher acidity.
  • Increasing temperature from 375 to 475 °C boosts reactant conversions but significantly raises catalyst deactivation.
  • Lower temperatures and specific crystal morphology enhance selectivity for para-xylene during the toluene alkylation.
  • The zsm-5 zeolite's 3D porous structure contributes to its stability and activity in the catalytic process.
