Engineered to deliver high physical strength, low dust generation, and optimal pore-opening precision. Select a formulation below to review critical specifications.
A 3A molecular sieve zeolite is an alkali metal aluminosilicate possessing an LTA-type (Zeolite A) crystalline framework. Synthesized by replacing sodium ions in the native 4A structure with potassium ions, it achieves an effective pore aperture of approximately 3 Ångströms (0.3 nm). This atomic-scale precision governs its kinetic selectivity, allowing the passage of water molecules (kinetic diameter ~2.65 Å) while excluding larger hydrocarbon species, solvents, and inert gases.
From a chemical kinetics standpoint, our 3A zeolites exhibit an exceptionally high affinity for moisture, operating efficiently under low partial pressures and elevated process temperatures. The highly crystalline aluminosilicate lattice acts as a powerful electrostatic attractor, pulling polar water molecules into its internal cage network (specifically the alpha-cages and beta-cages), while preventing co-adsorption of critical process streams like ethylene, propylene, ethanol, or natural gas hydrocarbons.
By preventing co-adsorption, 3A molecular sieves avoid hydrocarbon catalytic cracking and subsequent coking inside the pore channels during high-temperature thermal regeneration cycles. Consequently, this maximizes operational run-times, preserves structural integrity, and delivers ultra-low dew points down to -100°C (-148°F).
| Property Description | Standard Metric / Value | Industrial Target / Significance |
|---|---|---|
| Effective Pore Diameter | 3 Ångströms (0.3 nm) | Absolute exclusion of molecules > 3Å (e.g., Ethanol, Ethane) |
| Static Water Adsorption | ≥ 21.5% wt / wt | Maximum moisture loading capacity under standard equilibrium |
| Bulk Density | ≥ 0.72 g/mL | Optimizes bed packaging and volumetric mass transfer efficiency |
| Crush Strength (Beads / Pellets) | ≥ 80 N (spherical 1.6-2.5 mm) | Resists high pressure drops and mechanical stress in deep beds |
| Attrition Rate | ≤ 0.1% wt | Minimizes dust formation, preserving downstream compressors |
| Residual Moisture (LoI) | ≤ 1.5% wt (at 575°C) | Pre-activated, ready-to-load operational status |
3A Zeolite Molecular Sieves are critical components across diverse, highly demanding processing sectors worldwide.
In global bio-refineries, producing fuel-grade anhydrous ethanol requires breaking the ethanol-water azeotrope. Traditional distillation cannot exceed 95.6% purity. Our specialized 3A zeolites selectively extract the remaining water, pushing purity to ≥99.8% with zero chemical entrainment agents.
For architectural and residential glazing, 3A molecular sieves are filled into the spacer bars of double-glazed units. Because they reject nitrogen and argon, they prevent pressure changes, glass flexing, and mechanical failures, keeping dew points low and preventing condensation inside the unit.
In steam cracking facilities, the dehydration of unsaturated cracked gas streams (containing ethylene, propylene, and butadiene) must occur at low temperatures to avoid polymerization. Our 3A zeolite excludes these reactive olefins, preventing build-up in the catalyst pores and ensuring long-lasting performance.
