If finding the best way to produce polypropylene is a priority, CAT Crackers (Fluidized Catalytic Cracking Units) are a popular choice in upgrading gas and residue oils to gasoline diesel components. But caution is needed in reducing contamination from heavy metals, corrosion or fouling, because all of these issues can impact your facility’s profitability.


  • Control the increase of hydrogen in the CAT Cracker
  • Offer Antimony-based Nickle Passivators to reduce dry gas in the unit
  • Control fouling due to ash and other poly nuclear aromatic (PNA) compounds
  • Meet specifications for CBFS
