High Capacity Adsorption and Deep Drying adsorbent -- Molecular Sieve 13X APG
Time:2026-01-18
In the field of industrial adsorption, whether in air separation, natural gas processing or high-performance insulated glass manufacturing, the choice of adsorbent impacts operation
Molecular Sieve 13X APG represents a significant evolution in zeolite technology. Engineered with Advanced Particulate Granulation (APG), this grade delivers exceptional adsorption capacity, superior mechanical strength, and ultra-low dust generation setting a new benchmark for demanding applications worldwide.
So what is molecular sieve 13X APG?
13X APG is a premium grade member of the zeolite molecular sieve family, specifically engineered for high-precision adsorption and co-adsorption. The suffix APG stands for Advanced Particulate Granulation.
Unlike conventional molecular sieve 13X, 13X APG utilizes optimized binders and seed crystal technology to significantly reduce inactive filler content. This results in higher static water adsorption, lower attrition rate, and faster adsorption kinetics. As an X-type zeolite with a nominal pore size of 10Å, it effectively adsorbs not only water and carbon dioxide but also larger molecules such as sulfides, mercaptans, and bulky hydrocarbons.
High static water adsorption:
The static water adsorption capacity is around 28-29%, it means that every 100kgs of molecular sieve 13X APG can adsorb approximately 28-29kgs of water vapor. Almost 8% higher than standard 13X grade.
3. Manufacturing & Formulation Advantages
The core competitiveness of 13X APG lies in its binder-free forming process:
1). Seed Crystal Addition: Highly crystalline NaX seeds are introduced during synthesis to induce crystallization;
2). In-situ Conversion: Binders such as kaolin are transformed into active zeolite phases within the reactor, achieving total zeolite content ≥ 95%;
3). Spherical Forming: Advanced pan or pressure granulation technologies produce highly rounded beads with minimal airflow resistance.
Process Benefits: Higher adsorption capacity, significantly reduced dust generation and Extended service life.
4. Key Application Scenarios
4.1 Air Separation (PSA/VPSA Oxygen Generation)
13X APG is the premium adsorbent of choice for industrial Pressure Swing Adsorption oxygen plants. It efficiently adsorbs nitrogen while allowing oxygen to pass through.
- Advantage: High nitrogen adsorption capacity, excellent separation coefficient;
- Added Value: Low attrition rate ensures long-term operation without pulverization.
4.2 Natural Gas and Petrochemical Desulfurization
13X APG effectively adsorbs H₂S, mercaptans (RSH), and certain organic sulfur compounds from natural gas streams.
- Process Recommendation: Ideal for fine desulfurization applications with inlet sulfur content ≤ 50 ppm;
- Regeneration Method: Thermal purge at 180–260℃ or pressure swing regeneration.
4.3 Automotive and Architectural Insulated Glass
APG-grade material features extremely low dust and exceptionally uniform particle size, making it perfectly suited for automatic filling machines.
- Advantage: Prevents nozzle clogging and eliminates "bridging" or hang-up effects;
- Dew Point Assurance**: Guarantees cavity dew point ≤ -60℃.
4.4 Liquid Hydrocarbon Drying
Ideal for liquid-phase dehydration of aromatics and olefins. The 10Å pore opening allows aromatic molecules to enter the pore structure while capturing water, preventing co-adsorption losses of valuable product.
5. Packaging, Storage & Activation Guidelines
- Packaging: Vacuum-sealed aluminum foil bags (outer carton) or steel drum;
- Sealing Requirements: Exposure to ambient air should be ≤ 30 minutes;
- Storage Conditions: Store in a cool, dry warehouse and avoid direct sunlight exposure;
- Disposal: Spent material can be recycled as an adsorbent or disposed of as general non-hazardous industrial solid waste.
6. Common Technical Q&A
Q1: Can molecular sieve 13X APG be used for ethanol dehydration?
A1: Yes. However, if ethanol concentration exceeds 95%, 3A molecular sieve is generally recommended to prevent co-adsorption of ethanol.
Q2: Does switching from standard grade to APG grade require equipment parameter adjustments?
A2: No. Both grades share identical dimensions, enabling seamless drop-in replacement. APG grade often results in lower pressure drop due to higher mechanical strength.
Q3: Does 13X APG adsorb carbon dioxide?
A3: Yes. 13X APG exhibits strong CO₂ adsorption capacity and is often paired with 5A for combined CO₂/H₂O removal processes.
Q4: Do you offer customized particle sizes?
A4: Yes, we supply 1.6–2.5mm and 2.5–5.0mm spheres as well as 1.6mm and 3.2mm extruded pellets. Sample testing is supported.
Conclusion: Why Choose molecular sieve 13X APG?
For industrial clients prioritizing system stability, minimized maintenance frequency, and extended adsorbent lifespan, 13X APG represents a clear technological upgrade. From air separation to petrochemicals, from insulated glass to specialty gas purification, it is progressively replacing traditional adsorbents and becoming the silent standard in high-end applications.
