This type of reagent is used to passivate heavy metals in feedstocks that poison and reduce the effectiveness of catalysts in oil refining processes.
Metal passivators are substances or coatings that are used to prevent corrosion or oxidation of metal surfaces. They form a protective film on the metal surface that prevents the metal from interacting with the environment.
It is important to note that the choice of metal passivator depends on the type of metal, operating conditions and required protection. Our Company has extensive experience and a significant portfolio of solutions for this problem.
Example: Nickel passivator.
The fastest and most effective means of reducing the impact of nickel contamination is to introduce nickel passivation agents into the Catalytic Cracking feed stream. Passivation reduces the impact of nickel on Catalytic Cracking performance and operation by approximately 50%. Passivation reduces hydrogen evolution and coke formation and restores the operational flexibility of the catalytic cracker operation.
