Versatile Particle Design: Spherical/cylindrical/irregular shapes and 1-10mm size range adapt to fixed/fluidized/moving-bed reactors, enabling seamless process integration without custom equipment.
Optimized Pore Structure: 2-50nm average pore diameter and 0.3-1.5cm³/g pore volume balance active site exposure and mass transfer, critical for fast, efficient reactions.
Mechanical Robustness: Crushing strength ≥50N/cm (cylindrical) resists attrition, compression, and abrasion in industrial reactors, minimizing catalyst loss and maintenance downtime.
Broad Catalytic Compatibility: Supports diverse active components for VOCs oxidation, NOx reduction, hydrogenation, and chemical synthesis—adapting to varied industrial needs.
Scalable Performance: Consistent activity across particle sizes and batches enables scaling from pilot to industrial scale (10-100,000 Nm³/h gas flow) without performance degradation.
Cost-Effective Production: Mature manufacturing processes (extrusion, tableting) reduce costs by 30-50% vs. monolithic catalysts, ideal for high-volume applications.
Easy Replacement & Handling: Granular form allows gravity/pneumatic loading/unloading; spent catalyst is easily recovered for regeneration or disposal.
vs. Monolithic/Honeycomb Catalysts: 30-50% lower production cost, easier replacement (no reactor disassembly), and compatibility with existing granular reactor infrastructure—reducing retrofitting expenses.
vs. Powder Catalysts: Higher mechanical strength (no dust generation), lower pressure drop (avoids filter clogging), and simplified handling in industrial-scale operations.
Process Flexibility: Adapts to fixed-bed (high conversion), fluidized-bed (uniform temperature), and moving-bed (continuous regeneration) systems—covering diverse industrial requirements.
Customization Capability: Tailorable particle size, shape, active component loading, and pore structure for specific reactions (e.g., low-temperature VOCs oxidation, high-temperature reforming).
Cost-Efficient Lifecycle: 1-5 years service life and regenerability (thermal/chemical treatment) lower replacement frequency and total ownership cost vs. single-use catalysts.
VOCs Abatement: Pt/Pd-based spherical pellets (2-6mm) oxidize benzene, toluene, and solvents in petrochemical, coating, and printing industries (fixed-bed reactors, 200-400℃, ≥90% efficiency).
NOx Reduction: V₂O₅-WO₃/TiO₂ cylindrical pellets (3-5mm) for SCR systems in power plants, boilers, and diesel exhaust (300-400℃, ≥85% conversion).
CO Oxidation: Cu/Fe-based irregular pellets (1-3mm) in mining, metallurgy, and automotive auxiliary systems (150-300℃, ≥95% conversion).
Hydrogenation/Hydrogenolysis: Ni/Pt-based spherical pellets (4-8mm) for vegetable oil hydrogenation, aromatic hydrogenation, and ammonia synthesis (fixed-bed, 300-500℃).
Dehydrogenation/Reforming: Pt-Sn/Al₂O₃ pellets (2-4mm) for propane dehydrogenation (propylene production) and steam methane reforming (hydrogen production, 600-800℃).
Acid-Catalyzed Reactions: Zeolite pellets (3-6mm) for alkylation, isomerization, and catalytic cracking in oil refining (400-600℃).
Fuel Cell Catalysts: Pt/C pellet catalysts (1-2mm) for hydrogen purification and reformer gas treatment in fuel cell systems (200-300℃).
Biogas Upgrading: Ni-based pellets (4-6mm) remove CO₂ and H₂S from biogas, producing renewable natural gas (fixed-bed, 300-400℃).
