Bulk Molecular Sieves 5A | 2 bead sizes | multi-format

Molecular Sieve 5A

The Molecular Sieve 5A is a synthetic adsorbent material with a microporous crystalline structure, characterized by a pore diameter of 5 Å (0.5 nm). It is specifically designed for natural gas drying and desulfurization, and is used in industrial applications where prolonged adsorption cycles and high selectivity are required.

Technical Specifications

• Type: A LTA – Sieve 5A

Primary Areas of Use

• Production and industrial uses: natural gas drying and desulfurization (removal of H₂S and CO₂), separation of normal paraffins from branched and cyclic hydrocarbons.
• Drying systems: selective adsorption and separation of polar molecules from mixtures with absorbable but less polar molecules (e.g., preferred adsorption of H₂S in the presence of CO₂).
• Laboratories and quality control / analysis: drying and purification of gases and controlled humidity test environments; vacuum generation in thermal containers and sorption pumps.

Packaging and Availability

• Sealed polyethylene bottle and canister, 1 and 5 kg: suitable for application testing and frequent reorders.
• Sealed polyethylene drums: 15, 20, 25, and 30 kg.
• 135 kg metal drum: available with 1.6–2.5 mm grain size for immediate delivery and 2.5–5 mm only upon order.
• Big bag: for large volume industrial supplies.

Immediate availability, even in small packages, is ideal for those who require flexibility without having to manage large stocks.

Safety and Compliance

The Molecular Sieve 5A complies with European non-toxicity regulations. The product, new and unused, does not contain relevant quantities of substances whose limit values must be monitored in work environments.
