Gas Purification & Chemical Industry
Applications: Desulfurization, dearsenization, gas drying, catalyst carrier.
Common Specifications: Spherical/strip; particle size 2–4 mm, 3–5 mm, 4–6 mm, 5–8 mm; CuO content 3%–10%.
Key Indicators: Specific surface area 300–600 m²/g, water adsorption ≥25%, compressive strength ≥50 N/particle.
Functions & Principles: Silica gel provides high specific surface area; loaded Cu²⁺/CuO selectively adsorbs and catalytically oxidizes sulfides, arsine and other impurities.
