Metal Passivator Specifications
Supply values apply to the aqueous dispersion. CAS, EC number, formula and molecular weight identify the antimony pentoxide active component.
Commercial Information
Storage & Shipping
Storage Conditions
Store tightly sealed at room temperature in a cool, ventilated area. Protect from freezing, excessive heat and contamination. Keep separate from incompatible water-reactive chemicals and acidic reducing agents.
Shelf life
One year in sealed original packaging under the recommended storage conditions.
Packaging
1,360 kg IBC
Handling & Protection
Use controlled transfer with local extraction where mist can form. Wear chemical-resistant gloves and eye protection, avoid skin and eye contact and prevent antimony-containing releases to drains or surface water.
What Is Metal Passivator?
This metal passivator is an aqueous antimony pentoxide (Sb2O5, CAS 1314-60-9) dispersion for fluid catalytic cracking (FCC) units. Injected into the feed, antimony passivates nickel deposited on the cracking catalyst, which reduces the hydrogen and coke that nickel would otherwise produce.
The supply specification sets Sb2O5 at 26.0–28.0%, sodium at ≤500 ppm, pH at 4.00–6.00, density at 1.30–1.40 g/cm³ and viscosity at 3–8 cP, both at 20°C.
Treatment rate follows the feed nickel level and the refinery operating procedure. The dispersion is not regulated as dangerous goods. Protect it from freezing and contamination; shelf life is one year in closed original packaging.
As an FCC metal passivator supplier and exporter in China, ZXCHEM ships the pale yellow liquid in 1,360 kg IBCs.

Metal Passivator Applications
FCC nickel passivation
Antimony passivator injected into FCC feed to reduce the effect of nickel on the catalyst. Rate is set from feed metals.
Refinery metal management
Supports trials on catalyst activity, selectivity and hydrogen make in units processing high-metal feeds.
Catalyst additive blending
Aqueous inorganic dispersion for catalyst-additive systems. Dispersion stability and sodium tolerance are checked.
