Highly efficient silica-based adsorbent engineered for selective removal of polar impurities.
Consistent particle size distribution ensures uniform bed packing and predictable pressure drop in fixed-bed systems.
Low dust generation during handling, supporting improved operator safety and process cleanliness.
Thermally stable up to 600 °C, enabling regeneration under controlled high-temperature conditions.
Free-flowing granular form with optimized surface area (≈750 m²/g) for rapid mass transfer kinetics.
Purification of hydrocarbon streams in petrochemical refining (e.g., BTX feed pretreatment).
Removal of trace water and alcohols from solvent recycling loops in fine chemical manufacturing.
Polishing step in pharmaceutical-grade excipient drying processes.
Protection of sensitive catalysts in hydrogenation and oxidation reactors.
Moisture scavenging in electronic-grade gas drying systems (e.g., N₂, Ar, H₂).
