Lithium Zeolite Molecular Sieve | Li-X Zeolite for PSA Oxygen Generation

Lithium Zeolite Molecular Sieve | Li-X Zeolite for PSA Oxygen Generation

Product Overview

Lithium Zeolite Molecular Sieve (Li-X) is a high-performance lithium-exchanged zeolite adsorbent designed for oxygen generation by Pressure Swing Adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA) processes.

Li-X molecular sieve selectively adsorbs nitrogen from compressed or processed air, allowing oxygen-enriched gas to be produced. Its high nitrogen adsorption capacity and favorable nitrogen/oxygen selectivity make it suitable for applications ranging from compact household oxygen concentrators to large-scale industrial oxygen generation systems.

Shanghai Zixuan Technology provides Li-X molecular sieve in different particle-size grades to meet the requirements of various oxygen generation technologies and equipment configurations.

Product Grades & Applications

1. Li-X Molecular Sieve — 0.5–0.8 mm

For Household and Portable PSA Oxygen Concentrators

The 0.5–0.8 mm Li-X molecular sieve is designed for compact PSA oxygen concentrators, including household and portable oxygen generation equipment.

Its smaller particle size provides a relatively short diffusion path, supporting rapid nitrogen adsorption and desorption in compact adsorption beds. It is suitable for equipment requiring efficient gas separation within a limited adsorbent volume.

Typical applications:

• Household oxygen concentrators

• Portable and medical oxygen concentrators

• Compact PSA oxygen generation systems

2. Li-X Molecular Sieve — 1.6–2.5 mm

For Industrial VPSA Oxygen Generation Systems

The 1.6–2.5 mm Li-X molecular sieve is intended for industrial-scale oxygen generation systems using VPSA technology.

The larger particle size is suitable for industrial adsorption beds and can help reduce gas-flow resistance compared with smaller particles, subject to the actual bed design and operating conditions.

Typical applications:

• Industrial VPSA oxygen plants

• Oxygen supply systems for wastewater treatment

• Aquaculture oxygenation systems

• Metallurgy, glass manufacturing, and other industrial oxygen applications

Key Features

• High nitrogen adsorption capacity: Efficiently removes nitrogen from air to produce oxygen-enriched gas.

• Favorable N₂/O₂ selectivity: Supports effective nitrogen–oxygen separation.

• Rapid adsorption and desorption: Suitable for cyclic PSA and VPSA operation.

• Multiple particle-size options: Available for compact household PSA units and industrial VPSA systems.

• Potential for improved oxygen productivity: The appropriate Li-X grade may help improve system productivity and operating efficiency when matched to the equipment design.

Technical Selection

The final product grade should be selected according to the oxygen production capacity, target oxygen purity, adsorption pressure, cycle configuration, and adsorbent-bed design.
