Xylene feeds with low Bromine Index


TONSIL ® CO series catalysts have been establishing an outstanding status around the world. The Tonsil 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 years of experience in aromatics treatment and is committed to continuously improve these materials to adapt them to the increasing requirements of the petrochemical industry.

  • Longstanding experience around the world with multiple feedstocks
  • Very good cycle life even for heavy feedstocks and high amount of impurities
  • Less start-ups and shut-downs
  • High selectivity leads to less dealkylation
