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 (FAQ)
💬
What is the main function of this CO₂ absorbent?
This product is a high-performance CO₂ absorbent designed to chemically capture and remove carbon dioxide from gas streams. It is widely used in medical anesthesia circuits, diving equipment, submarines, spacecraft, and industrial gas purification systems.
💬
What is the CO₂ adsorption capacity of this product?
The CO₂ adsorption rate is greater than 25%, ensuring efficient removal of carbon dioxide in both medical and industrial applications.
💬
How should this CO₂ absorbent be stored?
It should be stored in a well-ventilated, low-temperature, and dry environment. Keep it away from acids and ammonia salts to prevent chemical reactions that could degrade product performance or cause safety hazards.
💬
What packaging options are available?
The product is available in multiple packaging sizes to suit different usage scales: 4.5 kg/drum, 5 L/drum, 16 kg/drum, and 20 kg/drum.
💬
Can this absorbent be used in laboratory settings?
Yes. In laboratory environments, it serves as a highly efficient desiccant and CO₂ scavenger for experiments requiring a CO₂-free atmosphere. It can also function as a basic catalyst or reactant in certain organic synthesis processes.
💬
What are the particle size specifications of this product?
The particle size is tightly controlled: material retained on a 4-mesh sieve must be less than 1.0%, and material passing through a 40-mesh sieve must be less than 2%. This ensures optimal flow and contact efficiency in various applications.
