Nickel passivators
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.
Discuss your application
Application and function
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.
Information for selection
- 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
Evaluation and technical review
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.
Discuss product selection
Share the application, operating conditions and requirements that matter to your evaluation. Product-specific properties, use guidance and handling information are provided in the relevant product data sheet and safety data sheet.
