Carrier/Stabilizer: Particle Size 1-5 mm, Crush Strength >50 N

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).

Engineering Analysis

Risks & Mitigation

Sintering of active species at high temperatures
Poisoning by impurities in feed
Mechanical attrition leading to fines generation
Pore blockage by coke or deposits

FMEA Triads

Trigger: High temperature operation
Failure: Sintering of active metal particles, loss of surface area
Mitigation: Use thermally stable carrier materials (e.g., alumina, zirconia); optimize calcination conditions

Trigger: Presence of sulfur or chlorine in feed
Failure: Poisoning of active sites, deactivation
Mitigation: Pre-treatment of feed; use poison-resistant carriers or additives

Trigger: Mechanical stress during handling
Failure: Attrition, generation of fines, pressure drop increase
Mitigation: Enhance carrier mechanical strength; use appropriate particle size and shape
