Products Description

Introduction Chemxin molecular sieve type 5a is an alkali alumino silicate; it is the calcium form of the type a crystal structure. Type 5a has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger. It is especially suitable for psa adsorber applications where it may be used for the separation of normal- and iso- paraffins (c4 to c6 species), in psa hydrogen purification and in oxygen concentrators. Regeneration Chemxin molecular sieve type 5a can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 5a molecular sieve, a temperature of 250-300°c is required. A properly regenerated molecular sieve can give moisture dew points below -100°c, or mercaptan or co2 levels below 2 ppm. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process. Size 5a - zeolites are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.

Buy Online Wholesale 13X Molecular Sieve from Supplier & Exporter in China

13X molecular sieve is an alkali aluminosilicate in sodium form with a faujasite crystal structure, offering a pore opening of approximately 10 angstroms (1 nm). It is designed to adsorb molecules with a kinetic diameter smaller than 10 angstroms while excluding larger ones. This grade is widely used in air separation, solvent drying, and gas purification applications due to its high adsorption capacity and thermal stability.

Compared to 3A or 4A sieves, 13X has larger pores, making it suitable for adsorbing larger molecules such as aromatics, freons, and branched hydrocarbons. It is commonly supplied as beads or pellets in moisture-resistant packaging to maintain performance during storage and transport.

For bulk buyers, 13X molecular sieve is available in industrial-grade formulations tailored for PSA systems, dehydration units, and hydrocarbon separations. Always verify compatibility with your specific process conditions, including temperature, pressure, and contaminant profile.

Best Fit & Nearest Alternatives

Best suited for:

Air separation plants requiring removal of CO₂ and moisture
Hydrocarbon processing for drying and purification of natural gas or LPG
Solvent recovery systems handling aromatics or polar solvents
Industrial gas generation where bulk adsorption capacity is critical

Not ideal for:

Applications needing sub-angstrom pore selectivity (e.g., ultra-fine gas separation)
High-temperature environments exceeding 350°C during regeneration without proper conditioning
Processes involving strong acids or bases that may degrade the aluminosilicate framework

13X offers larger pore size than 3A or 4A, enabling adsorption of bigger molecules like toluene or isoparaffins, but may sacrifice some selectivity compared to 5A for linear hydrocarbons. For oxygen generation, 13X is less efficient than LiLSX but more robust in humid conditions.

What Drives the Price

Pore size uniformity and adsorption capacity consistency
Regeneration stability and thermal shock resistance
Packaging type (e.g., moisture-barrier drums vs. bulk bags) and handling requirements
Certification status (e.g., food-grade, pharmaceutical compliance)

Pricing scales with order volume and minimum order quantity tiers. Request a quote based on your annual usage forecast to optimize cost per unit.

Lead Time, Shipping & Returns

Lead time: Typical lead time ranges from 15 - 30 days after order confirmation, depending on volume and customization. Confirm with supplier for exact timelines.
Shipping: Standard modes include 20' or 40' containers for bulk shipments, palletized bags for smaller orders, and express courier for samples. Freight terms (FOB, CIF) to be agreed per incoterm.
Returns & defects: Defective or non-conforming material may be returned within 30 days of delivery, subject to inspection and supplier approval. Buyer covers return shipping unless defect is confirmed. Always conduct on-site testing upon receipt.

Handling & Application Notes

Store in a dry, ventilated area away from strong acids or bases to preserve adsorption capacity.
Regenerate at 200 - 300°C under inert gas flow to restore performance; avoid thermal shock.
Pre-treat feed streams to remove particulates and oils to prevent fouling of the sieve bed.

Frequently Asked Questions (FAQs) on 13X Molecular Sieve

1. What is the typical water adsorption capacity of 13X molecular sieve?

Typical capacity ranges from 25 - 30% by weight at 25°C and 40% relative humidity. Exact values depend on granule size and prior regeneration history; confirm with supplier for your specific grade.

2. Can 13X molecular sieve be used to separate oxygen from nitrogen?

13X can adsorb nitrogen and other gases larger than oxygen, but it is not the most efficient choice for oxygen generation compared to specialized lithium-exchanged sieves. It is more commonly used for drying and bulk gas purification.

3. What is the recommended regeneration temperature for 13X?

Regeneration is typically performed at 200 - 300°C under a dry, inert gas flow. Exceeding 350°C may reduce long-term performance due to thermal stress on the crystal structure.

4. Is 13X molecular sieve suitable for acidic gas streams?

Not ideal for strong acid gases like HCl or SO₂ without prior neutralization or pretreatment, as prolonged exposure may degrade the aluminosilicate framework.

5. What packaging options are available for bulk shipments?

Standard options include 25 - 150 kg moisture-barrier drums, 500 - 1000 kg bulk bags, and custom sizes. Ask the supplier about desiccant liners or vacuum-sealed packaging for extended shelf life.

6. How should I handle and store 13X molecular sieve before use?

Store in a dry, ventilated area away from acids, bases, and direct sunlight. Keep sealed until use to prevent moisture uptake, which reduces adsorption efficiency.

7. Can 13X be used in liquid-phase applications?

Yes, but performance depends on solvent polarity and contaminant load. Conduct small-scale compatibility tests before full deployment, as some polar solvents or dissolved solids may reduce effective capacity or foul the sieve.

8. Does the supplier provide technical data sheets or certificates of analysis?

Yes, the supplier typically provides a certificate of analysis with each shipment, including moisture content, adsorption capacity, and granule size distribution. Request a sample data sheet before placing bulk orders.
