PRODUCT DESCRIPTION

Product Features

• High specific surface area and rich pore structure, excellent adsorption capacity for moisture and harmful gas.

• High mechanical strength and good abrasion resistance, not easy to pulverize during filling and application.

• Stable chemical property, insoluble in water, good resistance to weak acid and weak alkali.

• Adjustable particle size, good sphericity, low pressure drop when used in adsorption towers.

Application Fields

• Industrial Gas Drying: High-efficiency desiccant for compressed air, oxygen, nitrogen and natural gas, widely used in air separation, PSA gas generation and instrument air deep dehydration systems.

• Chemical Industry: Applied as professional catalyst carrier for chemical reactions and used for working solution purification, dealkalization and drying in hydrogen peroxide production.

• Water Treatment: Effectively removes fluoride, arsenic, heavy metals and residual chlorine from drinking water and industrial wastewater.

• Exhaust Gas Treatment: Adsorbs hydrogen fluoride, hydrogen sulfide, sulfur dioxide and volatile organic compounds from industrial flue gas to achieve exhaust purification.
