Nitrogen Removal of Benzene / Toluene / Xylene feeds with medium Bromine Index / Low Moisture

Edition Date :
October 29, 2015

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 high amount of impurities from Sulfolane / Morphylane
  • Less start-ups and shut-downs
