Alumina Packing Balls
Products Description
TECERA alumina packing balls serve as inert catalyst bed support media. These alumina packing balls ensure uniform fluid distribution in towers. These alumina packing balls feature excellent thermal stability. These alumina packing balls boost reaction and distillation efficiency.
Core Features & Benefits
TECERA alumina packing balls are high-purity inert alpha-alumina filling media, purpose-built for catalyst bed support and fluid distribution in chemical towers, distillation columns and fixed-bed reactors. Sintered from alpha-phase alumina powder, they directly solve core industry pain points including catalyst poisoning from low-grade carriers, bed fragmentation from thermal shock, and uneven flow reducing reaction efficiency.
High-purity inert formula: Alpha-phase crystal structure eliminates surface active sites and unwanted side reactions. High-purity grades control Fe₂O₃ ≤0.02% and Na₂O ≤0.03%, effectively preventing catalyst deactivation and meeting strict purity requirements for fine chemical and ethylene oxide production.
Superior strength & thermal shock resistance: Precision-formed and vacuum-sintered at 1600–1700°C for a dense, low-porosity structure. It withstands high reactor pressure and frequent thermal cycling without cracking, maintaining stable bed structure and reducing replacement frequency.
Uniform flow distribution: Precise spherical geometry and tight dimensional tolerance ensure even gas-liquid distribution and stable pressure drop across the bed, directly improving tower mass transfer efficiency and reaction consistency.
Flexible customization: Standard diameters range from 3 mm to 50 mm, with optional polished surface finish for high-purity conditions. Custom sizes, shapes and purity grades are available to match specific process requirements.
