Overview

Modification improved methanol conversion to light olefins in zeolites, suggesting enhanced catalytic properties.

Key Points

  • The modified zeolites achieved a methanol conversion rate exceeding 99%, showing significant catalytic advancement.
  • Selectivity for triene in the modified HZSM-5 zeolites reached 60.26%, indicating better efficiency in olefin production.
  • Total acid content decreased in modified samples, yet specific surface area and pore size increased, enhancing properties.
  • The hydrothermal method utilized for modification retained the MFI structure of the zeolites, maintaining their integrity.
