Product Description
Five-Toothed Spherical Catalyst Carrier (5-Lobe)
Engineered with a symmetrical 5-toothed (5-lobe) outer contour on a spherical core, this high-performance catalyst support breaks through the performance limits of standard spheres. It provides exceptional geometric surface area, optimized bed voidage, and minimized pressure drop for fixed-bed catalytic reactors.
Geometric Profile & Hydrodynamic Benefits
Visualizing the 5-toothed symmetry and its fluid dynamics optimization inside the reactor bed.
Target Applications & Reactor Suitability
Optimized for high-space-velocity and mass-transfer-limited catalytic processes.
Hydrotreating & HDS / HDN
Ideal substrate for CoMo and NiMo active phases used in diesel, naphtha, and vacuum gas oil hydroprocessing units.
- Suppresses bed plugging & fouling
- Maximizes active metal utilization
- Extends operational cycle length
Catalytic Oxidation & Hydrogenation
Tailored for exothermic synthesis and selective reactions requiring rapid heat dissipation and uniform distribution.
- Eliminates localized reactor hot spots
- Prevents secondary over-cracking
- Reduces compressor energy demands
Tail Gas Treatment & VOCs
Serves as a robust carrier for noble metals or metal oxides in environmental emission control and purification reactors.
- High thermal shock endurance
- Excellent mechanical durability
- Customizable bimodal pore distribution
Technical Specifications (TDS Data)
Standard physical and chemical property benchmarks for Five-Toothed Alumina Carriers.
Core Engineering Advantages
Key performance breakthroughs delivered by the 5-lobe spherical profile.
1. High Geometric Area & Dispersion
Offers 25%–35% more external surface area than smooth spheres, enabling higher active metal exposure and superior reaction conversion rates.
2. Low Bed Resistance (ΔP Reduction)
External flutes expand inter-particle space, reducing fluid friction and cutting reactor bed pressure drop by up to 30%.
3. Shortened Intra-Particle Diffusion
Optimized thickness across the lobes shortens reactant diffusion pathways to the core, minimizing side reactions and coking.
4. Exceptional Mechanical Integrity
The spherical base arch provides high mechanical strength, safely withstanding dense reactor loading and high-velocity fluid sweeps.
