Purpose

Metal passivators have two applications in the oil refining industry. (1) Substances used to inhibit the catalytic effect of active metal ions (copper, iron, nickel, manganese, etc.) on oil oxidation. It is often used in combination with antioxidants in light fuels such as gasoline, jet fuel, and diesel to improve the stability of the oil and extend the storage period. Commonly used ones include N,N’-disalicylidenepropanediamine. (2) In the catalytic cracking of heavy oil, antimony compounds are commonly used as substances used to inhibit the influence of heavy metals (nickel, vanadium, copper, etc.) contained in the oil on the catalyst activity.
