Metals Passivation

Nickel Passivation

Nickel is an impurity in the feed to FCC units. It competes with the FCC catalyst to promote dehydrogenation reactions, resulting in more hydrogen and coke formation and less production of valuable products. Nickel can also constrain throughput. Our nickel passivation solutions for FCCs inhibit its activity as a competitive catalyst, allowing the unit to proceed at top efficiency. Benefits include:

• More selective production
• Less demand on the wet gas compressor
• Less demand on the regenerator air blower
• Improved cat-to-oil ratio

Vanadium Passivation

Vanadium can behave as a competitive catalyst similar to nickel. Additionally, vanadium will combine with sodium to form a component that destroys the FCC catalyst's active sites. Without passivation, vanadium can lead to reduced catalyst specificity, increased cost in catalyst replacement and, potentially, increased coke and hydrogen production. Introduce our patented technology into your system to passivate vanadium and minimize its problems. Benefits are:

• Reduced costs of replacement catalyst
• More selective production
• Improved cat-to-oil ratio
• Increased production
• Capability to process feeds with higher vanadium
