Five-Toothed Spherical Catalyst Carrier
Engineered spheres with surface channels for maximum mass transfer
Five-lobe spherical carriers that combine high strength with enhanced external surface for diffusion-limited reactions.
Product Overview
The five-toothed (five-lobe) spherical catalyst carrier uses a non-circular cross-section with five longitudinal channels that dramatically increase geometric surface area while preserving the load-bearing core of a sphere. The result is superior mass transfer for diffusion-limited processes with lower pressure drop than plain spheres of the same hydraulic diameter.
This innovative geometry is increasingly specified for modern ultra-deep desulfurization and aromatics saturation units, where maximizing catalyst effectiveness at the pellet level drives performance.
Key Features
- Five-lobe geometry increases external surface by ~40%
- Reduced pressure drop versus solid spheres
- High mechanical strength retained in core
- Enhanced mass transfer for large molecules
- Ideal for deep HDS and saturation duty
