AI Overview
Colloidal Antimony Pentoxide (
) acts as an effective nickel passivator in Fluid Catalytic Cracking (FCC) units, minimizing hydrogen and coke production caused by metal contamination. It offers a safer, more efficient alternative to antimony trioxide, with specialized grades (e.g., Nyacol JL627S, PA550) providing small particle sizes (5-70 nm) and freeze-stabilized options.
Key Aspects of Colloidal Antimony Pentoxide Passivation
- Function: It is used to passivate nickel that deposits on catalysts in refinery FCC units, reducing the detrimental effects of heavy metal contamination.
