5A Molecular Sieve | Selective Adsorbent for N-Paraffin Separation & Gas Purification | Supplier for MENA & CIS

1. Product Introduction & Core Advantages

Aogochem 5A Molecular Sieve is a calcium-ion-exchanged Type A zeolite, engineered with a precise pore opening of 5 Angstroms (0.5 nm). This specific pore size grants it a unique shape-selective property, making it the industry-standard adsorbent for separating normal paraffins (n-paraffins) from their branched and cyclic isomers (iso-paraffins and aromatics). This separation is a fundamental and valuable process in petroleum refining and petrochemical industries to produce high-purity linear hydrocarbons for detergents, plastics, and solvents.

Beyond its premier separation function, 5A Molecular Sieve is a highly effective desiccant and purifier. It provides excellent co-adsorption of water (H₂O), carbon dioxide (CO₂), and hydrogen sulfide (H₂S), making it suitable for the simultaneous drying and sweetening of various gas streams. Aogochem's 5A sieve is manufactured for durability, featuring high crush strength to withstand deep bed pressures, excellent thermal stability for repeated regeneration, and consistent particle size for optimal kinetics and low pressure drop in industrial adsorption towers.

The table below details the key specifications of Aogochem's 5A Molecular Sieve, with the n-Hexane Adsorption being a critical indicator of its normal paraffin separation capability.

3. Primary Application Industries

The selective adsorption profile of 5A Molecular Sieve makes it indispensable in several high-value industrial sectors.

• Petrochemical & Refining (Normal Paraffin Separation): This is the signature application. It is used in Molex and similar processes to selectively adsorb n-paraffins (e.g., C10-C13) from kerosene or other fractions, producing linear hydrocarbons as premium feedstocks for biodegradable detergents (LAB) and solvents.

• Industrial Gas Production: It is a preferred adsorbent for Pressure Swing Adsorption (PSA) systems generating nitrogen from air, where it removes oxygen, moisture, and CO₂. It is also used in hydrogen purification streams to remove trace impurities.

• Natural Gas & Refinery Gas Processing: Effective for the simultaneous dehydration and partial sweetening of gas streams by removing water, CO₂, and H₂S, protecting pipelines and meeting specifications.

• Chemical Production: Used for drying and purifying various chemical feedstocks and products where selective removal of linear molecules or polar contaminants is required.

5. Handling & Operational Guide

• Loading: Ensure towers are clean and dry. Use proper methods to achieve a uniform, tightly packed bed and prevent particle fluidization or channeling during operation.

• Regeneration: Regeneration is typically achieved by temperature swing (TSA) using a hot, dry purge gas (e.g., nitrogen or light hydrocarbon) at 200-300°C, or by pressure swing (PSA). The specific cycle depends on the application (separation vs. purification).

• Storage: The product is hygroscopic. Store in a cool, dry place in sealed, original containers. Protect from atmospheric moisture to prevent premature capacity loss.

• Safety: Refer to the Safety Data Sheet (SDS). Use standard PPE (gloves, safety glasses) when handling to prevent irritation from dust. Ensure adequate ventilation in working areas.
