MOLECULAR  SIEVE DESCRIPTION

Zeolite molecular sieves are crystalline microporous materials with a uniform pore structure. They function as “molecular sieves” by selectively adsorbing molecules small enough to pass through their pores, while excluding larger ones—enabling precise separation by size and shape.

The framework is composed of SiO₄ and AlO₄ tetrahedra interconnected via oxygen atoms, forming a well-defined three-dimensional network with molecular-scale cavities and consistent pore channels.

Thanks to their structural diversity, exceptional hydrothermal stability, and unique selectivity, zeolite molecular sieves are widely used in petroleum refining, gas separation, catalysis, and other industrial processes—where they play an essential role in enhancing efficiency and enabling key technologies.

[Application] 

Wood products, automobile, shipbuilding, home appliances, container production factory spray paint, painting workshop of organic waste gas purification, can also be used in shoes, rubber, printing, chemical plastics, cable, enameled wire and other assembly line supporting equipment use

ADVANTAGES  OF  MOLECULAR  SIEVES    

1.GOOD HYDROTHERMAL STABILITY ：Exhibits significant adsorption capacity even under relatively high temperatures and high humidity conditions.

2.PRECISE SELECTIVITY：Its uniform internal pore size distribution enables effective molecular recognition, thereby significantly enhancing the molecular sieve's selective adsorption capacity for VOCs molecules.

3.DESORPTION DIVERSITY：As a non-flammable material, it allows for desorption through various methods such as pressure swing, microwave, and hot air desorption.

4.HIGH ADSORPTION CAPACIT：The material possesses a highly porous internal structure and an extensive specific surface area, enabling it to adsorb contaminants hundreds of times its own volume.

5.TUNABLE HYDROPHOBICITY：The hydrophilicity/hydrophobicity of the molecular sieve can be adjusted by modifying its framework silicon-to-aluminum ratio. Molecular sieves with a high silicon-to-aluminum ratio exhibit excellent hydrophobic properties, effectively reducing competitive adsorption of water against VOC molecules under certain humidity conditions.

6.REVERSIBILITY：It exhibits reversible adsorption of both liquids and gases.

Desorption Advantage — Customer Demonstration

Before Desorption: Visible accumulation of dust particles adhered to the molecular sieve surface.
After High-Temperature Desorption: The molecular sieve surface is clean with little to no adhered substances.This demonstrates effective treatment of inadequately pretreated waste gas, with desorption restoring the molecular sieve's original performance.

Desorption Advantage — Visual Results of High-Temperature Regeneration

Before Desorption: The molecular sieve appears yellow with black traces, visibly saturated with adsorbed organic compounds and oil stains.
After High-Temperature Desorption: The surface is clean and free of attachments, indicating thorough regeneration.This process effectively handles inadequately pre-treated exhaust gas or incomplete on-line desorption, fully restoring the molecular sieve's original performance after regeneration.
