Engineered adsorbents customized to withstand harsh solvent profiles and achieve ultra-low moisture ppm levels.
Overcoming the limitations of traditional distillation with high-selectivity zeolitic molecular sieve matrices.
In modern chemical, pharmaceutical, and petrochemical manufacturing, organic solvents play a critical role as reaction media, cleaning agents, and processing fluids. However, the presence of trace moisture—even at parts-per-million (ppm) levels—can critically degrade reaction yields, catalyst performance, and product quality. Traditional separation methods such as fractional distillation are highly energy-intensive and often struggle to break azeotropic solvent mixtures (such as ethanol-water, isopropanol-water, or acetonitrile-water) without introducing hazardous entrainers.
JOOZEO’s synthetic molecular sieve and adsorbent engineering technologies offer an efficient, green, and highly cost-effective alternative. By utilizing thermodynamic and kinetic principles, our specialized porous materials selectively capture water molecules (kinetic diameter ~2.65 Å) while completely excluding organic solvent molecules. This precise size-exclusion technology enables industrial manufacturers to achieve up to 99.99% solvent purity, drastically lowering carbon footprints and operational costs.
Understanding the molecular properties driving efficiency in continuous dehydration loops.
Designed for absolute moisture extraction from highly polar solvents like ethanol and methanol. The 3A type features a crystal pore opening of approximately 3 Å, perfectly restricting larger hydrocarbon frameworks while trapping water molecules within its aluminosilicate cage.
Possessing high surface area-to-volume ratios, these materials are optimized for bulk moisture pre-treatment, acidic gas adsorption, and preventing trace degradation products. Alumina Silica Gel hybrids provide robust thermal and chemical stability under varied pH profiles.
Catalyst beds and support media designed to resist thermal shock and crushing loads in massive vertical adsorption vessels, ensuring uniform flow distribution and preventing channeling of volatile organic compounds.

|---|---|---|---|---|
| Molecular Sieve 3A | 3.0 | Ethanol, Isopropanol, Methanol, THF Dehydration | < 50 ppm (down to 5 ppm) | 200 - 250 |
| Molecular Sieve 4A | 4.0 | Acetone, Ethyl Acetate, Hexane Drying | < 100 ppm | 220 - 280 |
| Activated Alumina | Trans-porous | Gaseous Solvent Drying & Acid Extraction | < 150 ppm | 180 - 220 |
| Silica Gel JZ-SG-B | 20 - 100 | Bulk Drying, Static Packaging, Air Separation Feed | < 500 ppm | 120 - 150 |
