What is a Molecular Sieve, and How Does It Work?
Do you intend to buy molecular sieves in bulk? Or are you looking for suitable absorbents for gas drying, oxygen and nitrogen separation, and air purification? We are here to help you! As a leading manufacturer, we offer all kinds of molecular sieves with an excellent ability to absorb moisture and separate gases at the best quality and competitive price.
Our molecular sieves are manufactured in such a way that they can be well used to remove moisture and separate gases in various industries. If you need this absorber for special applications or general ones, ActivatedChem has the ability to produce the right product for you according to your needs.
Molecular sieves are synthetic zeolites with tiny pores. They are needed for industries that require gas separation, water treatment, and removal. These adsorbents can absorb molecules of a certain size, so to choose the right adsorbent, you must know which one is suitable for your industry before buying.
In 2025, according to the country's customs statistics, the value of zeolite molecular sieve exports from Germany to different countries was equal to 103 million dollars, and from the United States, it was equal to 59 million dollars. This amount of exports has been increasing for most countries, which shows the growth of demand for bulk molecular sieve.
Why Is Molecular Sieve Better Than Other Desiccants?
The reasons for the superiority of Zeolite Molecular Sieve are:
✅ Compared to activated alumina and silica gel, it has a higher absorption capacity.
✅ Due to its better thermal stability, it is used for industrial applications.
✅ It can be Regenerated, which means you can reuse it.
How Do I Choose the Right Zeolite Molecular Sieve for My Needs?
Choosing the right molecular sieve depends on your application and intended use. Here are the key factors to consider:
✔ Pore Size: Depending on your need for drying, gas separation or air purification, this size is very important.
✔ Bulk density and crushing power: In high-pressure systems, it is better to use absorbents with a higher density so that they last longer.
✔ Rebuildability: Select an adsorbent that can be regenerated and reused after heating.
✔ Supplier and Manufacturer Reliability: Does the supplier provide industry-standard quality? Of course, we offer this guarantee. Due to our supply power, you can also buy molecular sieves from us in bulk.
Which Molecular Sieve Type is Best for My Application?
Depending on your needs, different types of zeolite molecular sieves are available:
| What Do You Need? | Best Molecular Sieve Type |
|---|---|
| Drying polar liquids & gases (e.g., ethanol, natural gas) | 3A |
| General moisture adsorption | 4A |
| Oxygen & nitrogen separation in PSA systems | 5A |
| Air purification & CO₂ removal | 13X |
