Passivateurs de nickel

Nickel passivators are used in FCC operations to address unwanted catalytic effects of nickel carried with the feed. Treatment selection is based on metals loading, catalyst information and unit operating constraints.

Application et fonction

Nickel associated with FCC catalyst can promote unwanted dehydrogenation, contributing to hydrogen and coke formation. Passivation treatment is intended to limit nickel-related activity.

Chemical approach and delivery characteristics depend on formulation. Select treatment within the existing catalyst and metals-management program.

Informations pour la sélection

  • Nickel analyses for feed and available catalyst samples
  • Hydrogen and coke trends, feed changes and unit constraints
  • Current catalyst program, other additives and injection facilities

Évaluation et révision technique

Establish a baseline for nickel-related operating indicators before a monitored trial. Review response alongside feed quality, catalyst changes and operating conditions.

Changes in throughput or product distribution should be assessed separately. Use the metals data and operating concern to define the evaluation.
