Application
-
🏥1. Medical AnesthesiaIn anesthesia and intensive care, it absorbs exhaled CO₂ in the circulation loop of anesthesia machines and ventilators, allowing the exhaled gas to be re-inhaled after replenishment with oxygen and anesthetic gas, achieving "closed-loop anesthesia" and significantly conserving anesthetic gas and oxygen.
-
🤿2. Diving and Confined SpacesUsed in confined environments such as diving breathing apparatus (e.g., rebreathers), submarines, spacecraft, and hyperbaric oxygen chambers to purify air and maintain breathable oxygen levels and safe CO₂ concentrations.
-
🏭3. Industrial Gas PurificationIn chemical and petroleum industries, it purifies hydrogen, nitrogen, inert gases, etc., removing acidic impurities such as CO₂ and H₂S.
- Biogas/Natural Gas Purification: In biogas or natural gas treatment, it removes CO₂ to improve the calorific value and purity of the fuel.
- Flue Gas Treatment (Small-scale or specific scenarios): Used as an alkaline absorbent to treat acidic gases.
-
🔬4. Laboratory Applications
- Drying and purification: Used as a highly efficient desiccant, or for experiments requiring a completely CO₂-free environment.
- Synthetic reactions: Used as a basic catalyst or reactant in certain organic synthesis processes.

Frequently Asked Questions
❓ What is the CO₂ adsorption rate of this product?
The product has a CO₂ adsorption rate of greater than 25%, making it highly effective for use in medical, industrial, and laboratory environments where CO₂ removal is critical.
❓ Is this product suitable for use in medical anesthesia machines?
Yes. This product is specifically designed for use in anesthesia machines and ventilators. It absorbs exhaled CO₂ in the closed circulation loop, enabling re-inhalation of gas after oxygen and anesthetic replenishment, which helps conserve anesthetic gas and oxygen during procedures.
❓ Can it be used in diving rebreathers or submarines?
Yes. The product is well-suited for confined and closed-loop breathing environments such as diving rebreathers, submarines, spacecraft, and hyperbaric oxygen chambers. It effectively purifies air and maintains safe CO₂ and oxygen levels.
❓ What packaging sizes are available?
The product is available in the following packaging options: 4.5 kg/drum, 5 L/drum, 16 kg/drum, and 20 kg/drum, catering to different usage scales from laboratory to industrial applications.
❓ How should this product be stored safely?
It should be stored in a ventilated, low-temperature, and dry environment. It must be kept separately from acids and ammonia salts to prevent chemical reactions or product degradation.
❓ What are the particle size specifications of this product?
The particle size is controlled to ensure quality: material retained on a 4-mesh sieve is less than 1.0%, and material passing through a 40-mesh sieve is less than 2%. This ensures consistent granule size for optimal performance in various applications.
