Component Specifications

Definition
A carrier/stabilizer is a solid material, often porous, used to support and disperse catalytic active components (e.g., metals, enzymes) to enhance their stability, activity, and selectivity. It prevents agglomeration, provides mechanical strength, and facilitates catalyst recovery and reuse. Common carriers include alumina, silica, zeolites, and carbon-based materials.
Working Principle
The carrier provides a high surface area substrate for the deposition of catalytic active species. Through physical adsorption, chemical bonding, or encapsulation, the active components are anchored onto the carrier surface, preventing sintering and deactivation. The carrier may also participate in the reaction by providing acid/base sites or influencing electron transfer.
Materials
Alumina (Al2O3), Silica (SiO2), Zeolites, Activated Carbon, Titania (TiO2), Zirconia (ZrO2), Magnesia (MgO), or composite oxides. Specifications include surface area (50-1000 m²/g), pore volume (0.2-2 cm³/g), and particle size (0.1-10 mm).
Technical Parameters
  • Pore Volume 0.5-1.5 cm³/g
  • Bulk Density 0.4-0.8 g/cm³
  • Surface Area 100-500 m²/g
  • Particle Size 1-5 mm
  • Crush Strength >50 N
Standards
ISO 9277, ISO 15901, ASTM D3663
