Al Silica Gel (Silica-Alumina Gel)

Description

Al silica gel is a colourless or yellowish transparent / translucent particle, non-toxic and tasteless. Chemically stable; insoluble in water, inorganic acid and other organic solvents. Compared with narrow pore silica gel, its low-humidity capacity is equivalent (e.g. RH10%, RH20%), but its high-humidity capacity (e.g. RH80%, RH90%) is 6–10% higher, and its thermal stability is more than 150 °C higher — very suitable as a temperature-swing adsorption and separation agent.

Structure & key data: Al2O3 0.5–5% · Pore volume 0.4–0.6 ml/g · Specific surface 600–800 m²/g

Applications

Natural gas dehydration
Temperature-swing adsorption separation of light hydrocarbons
Petroleum industry catalyst and catalyst carrier
Industrial desiccant, liquid adsorbent and gas separation
