Pore Structure : Uniform, size-selective pores (e.g., 3-10 Å) arranged in a crystalline lattice. 2.

Classification by Pore Size Type Pore Size (Å) Cation Form Key Applications 3A 3 K+ (Potassium A) Drying polar liquids (e.g., ethanol) 4A 4 Na+ (Sodium A) Air/gas dehydration, hydrocarbon separation 5A 5 Ca²+ (Calcium A) N2/O2 separation, petrochemical refining 13X 10 Na+ (Sodium X) CO2 removal, natural gas purification Y-Type 7.4 Na+ (Sodium Y) Catalytic cracking, VOC adsorption 3.

Key Properties High Adsorption Capacity : Especially for polar molecules (H2O, CO2). Selectivity : Size- and polarity-based separation (e.g., excludes molecules larger than pores). Thermal Stability : Stable up to 600°C , enabling regeneration via heating. 4.

Industrial Applications Gas Dehydration : Removes H2O from air, natural gas, and refrigerants. Petrochemicals : Separates hydrocarbons (e.g., n-paraffins from iso-paraffins). Environmental Protection : Adsorbs H2S, SO2, and VOCs from exhaust gases.

Other Uses : Fuel Ethanol Production : 3A sieves for azeotropic dehydration. Oxygen Concentrators : 5A/13X sieves for N2/O2 separation. 5. Handling & Regeneration Storage : Seal in dry conditions to prevent moisture absorption. Regeneration : Heat to 250-350°C under inert gas to restore adsorption capacity.

Application Adsorption Separation Applications of Zeolite Molecular Sieves 1.

Mixed Xylene Separation Challenge: Mixed xylene (containing ethylbenzene, p-xylene, m-xylene, o-xylene) is typically sold as low-value solvent Traditional separation methods (distillation, crystallization) are energy-intensive and inefficient Molecular Sieve Solution: Zeolites offer selective adsorption based on molecular size/shape differences Particularly effective for separating p-xylene (most valuable isomer) Advantages over conventional methods: ✓ Lower energy consumption ✓ Compact equipment footprint ✓ Higher purity yields 2.

Nitrogen/Oxygen Separation (PSA Systems) Separation Mechanism: Exploits stronger N2 adsorption due to: • Higher N2 polarizability (quadrupole moment) • Stronger interaction with zeolite cations • Greater van der Waals forces Optimized Zeolite Systems: Type Characteristics Limitations LiA High N2/O2 selectivity Poor thermal stability Mixed-cation A Balanced selectivity/stability Complex preparation Low-Si X Excellent stability Slightly lower capacity Product Parameters Name Unit Molecular Sieve shape - strip type ball diameter mm size ratio up to grade % ≥98 ≥98 ≥96 ≥96 bulk density g/ml ≥0.60 ≥0.60 ≥0.60 ≥0.60 wear ratio % ≤0.20 ≤0.25 ≤0.20 ≤0.20 crushing strength N ≥45/cm ≥60/cm ≥45/p ≥45/p static H2O adsorption % ≥20 ≥20 ≥20 ≥20 water content % ≤1.5 ≤1.5 ≤1.5 ≤1.5 Detailed Photos Molecular sieve is widely used,not only as an excellent adsorbent in organic chemical industry and petrochemical industry,for gas dehydration, but also in the waste gas purification increasingly received attention.in addition,due to its high adsorption capacity, high selectivity,high temperature resistance and other characteristics,molecular sieves play an important role in many industrial fields.

Molecular sieve is very easy to absorb water, should not be directly exposed to the air when stored,should be placed in a dry place sealed storage.if moisture absorption,should be regenerated after use. Packaging & Shipping FA istrict, Pingxiang City, Jiangxi,China.welocme your visiting.
