MCM-41 Molecular Sieve

MCM-41 Molecular Sieve MCM-41 Molecular Sieve (silica, mesostructured) - MCM-41 belongs to one dimension pore structure. It has uniform aperture, and high specific surface area (900-1000 m²/ g), and good adsorption capacity (1.0ml/g), and is more suitable for organic molecule speedy diffuse than zeolite and phosphate & aluminates etc. As a result, it is able to macromolecule, especially heavy oil organic molecule in petrochemical process enough room and effective acidity to proceed. And it could also adjust aperture and acidity consistency & intensity, indicating that it has strong latent value in separation processes of residuum catalytic cracking, heavy oil hydrogenated, fluid oil hydrogenated, alkylation, olefinic polymerization, isolation of CO₂-CH₄.
Technical Parameter of MCM-41 :

• Average Pore Diameter 3.5±0.2 nm
• BET Surface Area  ¥900 m²/g
• Pore Volume  ¥0.8 cm³/g Na₂O
• Content ¤0.5%
