Xylene feeds with low Bromine Index / Low Moisture


TONSIL ® APT series catalysts have their basis on the expertise which was gained with the TONSIL® CO series. The Tonsil APT series has multiple products for each process to meet the different requirements in terms of activity and selectivity. Generally, Tonsil catalysts contain less side reaction active sites and have high surface area and superior pore properties. Those properties ensure the long cycle time of Tonsil catalysts, thus reduce the number of change outs and operation cost, increase the operation efficiency and reduce energy consumption. Clariant has gained now also with APT series years of experience in aromatics treatment.

TONSIL® APT series has several advantages over the TONSIL® CO series.
  • No sand grading is required - Loading procedure is less complex without sand grading
  • Higher bulk density
  • Longer cycle life
  • Less start-ups and shut-downs
  • Lower pressure drop
  • Lower energy consumption
  • Finally leads to lower CAPEX and OPEX over the whole year
    • Longstanding experience around the world with multiple feedstocks
    • Excellent cycle life
    • Less start-ups and shut-downs
    • High selectivity leads to less dealkylation
    • Easy reactor loading procedure
    • Low Moisture
