Silica Gel For PSA
Diameter: 1-3mm, 1-4mm, 2-4mm, 2-5mm, 3-5mm
Description
Tlhe appearance is yellowish, hard glassy transparent or translucent particles. The chemical molecue is: mSiO2·nH2O, which is similar to Type A silica gel in the series of silica gels, but is adsorption capacity and adsorption index are far greater than Type A silica gel.
Application
Pressure swing adsorption silica gel not only has a strong affinity for water, but also has strong adsorption capacity for hydrocarbons and CO2. Pressure swing adsorption silica gel is mainly used for the recovery, separation and purification of carbon dioxide gas. It is used in the ammonia synthesis industry, food and beverage processing industry, etc. to produce carbon dioxide. It can be used for PSA hydrogen extraction, PSA CO purification, PSA methane concentration, PSA decarbonization, and PSA purification. CO2, PSA concentrated ethylene, desulfurization, dealcoholization, drying and other types of equipment; it can also be used for drying, moisture-proofing and dehydration and refining of organic products.

Silica-alumina Gel-AN
Chemical Formula: mSiOznAlzO;·xH₂O
Description
Stable chemical properties, non-combustible, insoluble in any except strong alkali and hydrofluoric acid, Any solvent, with stronger surface polarity than fine-pore silica gel, adsorption and separation. Performance is better than fine-pore silica gel, and thermal stability is good.
Applications
This product has the characteristics of high specific surface area and strong drying ability. Versatile adsorbent due to its high compressive strength and low wear.
With longer service life than ordinary fine ball silica gel, it has excellent performance and price advantage. This product is mainly used for:
dry compressed air, dry natural gas, Dry gas, dry liquefied gas.
If there may be liquid water in the system, it is recommended to add 20% (weight Amount ratio) of water-resistant silica-alumina glue is used as a protective layer.
Widely used in industrial oxygen production, hydrogen production, carbon dioxide purification, Natural gas purification, refrigerant drying, insulating glass, gas separation and purification, Nuclear wastewater treatment, oxygen-enriched combustion, steel and non-ferrous metal smelting, pneumatic Braking, petrochemical, coal chemical and other industries and fields.
