Semi-Regenerative Reformer Catalyst (Fixed-Bed)
Fixed-Bed
A specialized fixed-bed catalyst (typically Platinum-Rhenium) used in semi-regenerative reforming units. It is designed to operate under varying pressure and temperature conditions over long cycle lengths between shutdowns.
Key Features
- High Stability & Low Coking: The Rhenium ($Re$) promoter significantly improves the catalyst's stability against coke formation, allowing for extended run times.
- Balanced Activity: Provides a precise balance between acid-site isomerization and metal-site dehydrogenation to maximize liquid yield.
- Excellent Thermal Resilience: Maintains its pore structure and metal dispersion even under the high-temperature end-of-run conditions.
- Proven Reliability: Engineered for consistent performance in older-generation fixed-bed reactors.
