FCC Passivating Agent
Heavy Metal Passivation Solution for FCC Catalysts in Oil Refining
Petroleum Passivator is a high-performance additive specifically developed for Fluid Catalytic Cracking (FCC) and residue hydrotreating processes. It effectively neutralizes the harmful effects of heavy metals such as nickel, vanadium, iron, and copper, thereby extending catalyst life, improving product yield, and reducing coke formation.
Product Overview
In oil refining, heavy metals like Ni and V in crude oil residues poison FCC catalysts, leading to reduced activity and excessive dry gas or coke. Our Petroleum Passivator forms stable compounds with these metals, immobilizing their catalytic activity, and protecting the zeolite catalyst structure.
Formulated using antimony-based, magnesium-based, or composite metal agents, our passivators are thermally stable, highly dispersible, and customizable based on specific crude characteristics.
