ZATARIS‑21: Isomerisation EBD‑Type Catalysts

Aromatics plant operators can enhance activity and selectivity when compared with industry-standard EBD catalysts through the use of ZATARIS‑21, Shell Catalysts & Technologies’ latest generation XI‑EBD catalyst.

Depending on the feed, operating conditions, product requirements and profit considerations, the ratio of each catalyst per bed can be tailored to provide greater feed flexibility.

In comparison with industry-standard EBD catalysts, ZATARIS‑21 offers standout performance in terms of activity, selectivity and ring retention.

Results include: 

  • lower operating temperatures;
  • reduced CO₂ emissions;
  • longer cycles;
  • lower xylene losses; and
  • lower aromatic ring losses.
