Introduction
Molecular sieves have transformed various industrial sectors due to their incredible adsorption properties. In the world of industrial processes, efficiency and accuracy are key. For processes like air separation, oxygen concentration, and refrigeration, the use of molecular sieves is common. Among these, JLOX series molecular sieves – including JLOX-100, JLOX-300, and JLOX-500 – have been recognized for their superior performance. As Lithium Molecular Sieves, these products offer unique characteristics that make them highly suitable for specific applications.
Understanding Molecular Sieves
Molecular sieves are a type of zeolite, a crystalline substance made of aluminosilicate minerals. They are called sieves due to their porous structure, with pores of uniform sizes that allow them to selectively sieve out particles of specific sizes. Among these, the JLOX series, a zeolite oxygen sieve, stands out due to its high nitrogen adsorption capacity and nitrogen-oxygen selectivity.
Molecular sieves are materials with incredibly small holes, or pores, of precise and uniform size. These pores allow small molecules to pass while larger molecules get sieved out, hence the name “molecular sieve.” JALON molecular sieves are renowned for their high selectivity and adsorption capacity, making them essential in diverse applications, including cryogenic air separation, gas purification, and pressure swing adsorption (PSA) oxygen production.

JLOX-100 Series
JLOX-101 and JLOX-103 are part of the JLOX-100 series, which are primarily used in oxygen concentrators. The main differences between the two lie in their diameter and crush strength. JLOX-101, with a diameter of 0.4-0.8 mm, is perfect for applications that require smaller sieve sizes. On the other hand, JLOX-103, with a diameter of 1.3-1.7 mm, offers a higher crush strength, making it more robust and suitable for applications where durability is key.
JLOX-300 Series
Next up, we have the JLOX-300 series, including JLOX-300 and JLOX-305, which are known for their use in cryogenic air separation pre-purification units. These molecular sieves have an exceptional adsorption performance under low partial pressure, leading to increased efficiency and extended adsorption cycles. JLOX-305 is a larger bead version of the JLOX-300 molecular sieve, used in cryogenic air separation pre-purification units. Its larger size of 3-5 mm allows for increased flow and throughput in larger systems while still maintaining excellent adsorption properties. It can demonstrate its adsorption performance under low partial pressure conditions, making it an efficient choice for cryogenic air separation applications.
JLOX-500
Lastly, the JLOX-500 series, which includes JLOX-500 and JLOX-501, are specially designed for the pressure swing adsorption oxygen production process. They boast a high nitrogen adsorption capacity and an excellent nitrogen and oxygen separation coefficient, making them a great choice for oxygen generation. JLOX-501 is designed specifically for use in PSA portable oxygen generators in the medical oxygen market. With a smaller diameter of 0.4-0.8 mm, it’s designed to maximize surface area for adsorption, allowing oxygen purities up to 93%±3%. Its design makes it a perfect fit for portable medical oxygen concentrators.
13X
13X molecular sieves are perfect for the removal of carbon dioxide and moisture from air and other gases. They offer significant advantages in applications like cryogenic air separation and air drying due to their excellent moisture removal capability.
Detailed Comparison: JLOX-100, JLOX-101, and JLOX-103
Even slight differences in molecular sieve specifications can lead to substantial performance variations. Here’s a closer look at JLOX-100, JLOX-101, and JLOX-103:
JLOX-100: This molecular sieve is characterized by a higher nitrogen adsorption capacity, high nitrogen with oxygen selectivity, and easy desorption. Its nitrogen adsorption capacity is 2-3 times larger than the A type oxygen enrichment molecular sieve, making it particularly effective in VPSA oxygen concentrator devices. It also boasts good wear resistance and a longer service life, contributing to lower operating costs and energy consumption.
JLOX-101: Similar to JLOX-100, JLOX-101 also features a higher nitrogen adsorption capacity and high nitrogen with oxygen selectivity. Its smaller diameter (0.4-0.8 mm), however, makes it particularly suitable for applications where smaller particle size is needed, such as PSA portable medical oxygen generators 1-5L/Min.
JLOX-103: With a diameter of 1.3-1.7 mm and a similar nitrogen adsorption capacity and selectivity to JLOX-101, JLOX-103 is also designed for oxygen production. It, however, has a larger diameter which makes it suitable for use in systems where larger bead sizes are required for optimum performance.
