Indian Oxides and Chemicals Antimony Pentoxide IND STAR CPO-35 (S)

Applications & Uses

Applications

• Ind star CPO – 35 (S) is an effective passivator against trace amounts of Nickel in FCC feed.
• Ind star CPO – 35 (S) is added to FCC feed to reduce the adverse effects of Nickel on FCCU catalyst. Traces of Nickel in the FCC feed get incorporated in to the catalyst as the sulfide and act as re-hydrogenation catalyst. Too much hydrogen overloads the gas plant and limits through put. Antimony also is incorporated into the catalyst and poisons Nickel’s ability to act as a de-hydrogenation catalyst.
• Although the hydrogen effect is the most predominant harmful effect, Nickel also increases coke make and decreases gasoline conversion. Ind star CPO – 35 (S) metal passivator counter acts these two lesser effects of Nickel on FCCU catalysts.
• Ind star CPO – 35 (S) metal passivator is injected into the feed to the FCC at an Sb/Ni wet ratio of 0.25 – 0.55. Optimization is based on hydrogen make per barrel.
