WebThe meaning of MOLECULAR SIEVE is a crystalline substance (such as a zeolite) characterized by uniformly sized pores of molecular dimension that can adsorb small molecules and is used especially in separations. A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can. As a mixture of molecules migrate through the stationary bed of porous, semi-solid … See more Molecular sieves can be microporous, mesoporous, or macroporous material. Microporous material (<2 nm) • Zeolites (aluminosilicate minerals, not to be confused with aluminium silicate) • Porous glass: … See more Methods for regeneration of molecular sieves include pressure change (as in oxygen concentrators), heating and purging with a carrier gas (as when used in ethanol dehydration), … See more • Chemical formula: Na2O•Al2O3•2SiO2•9/2H2O • Silica-alumina ratio: SiO2/ Al2O3≈2 Production Production of 4Å is relatively straightforward and … See more Molecular sieves are available in different shape and sizes. But the spherical beads have advantage over other shapes as they offer lower pressure drop, are attrition resistant as they do not have any sharp edges, and have good strength, i.e. crush force required per … See more Molecular sieves are often utilized in the petroleum industry, especially for drying gas streams. For example, in the liquid natural gas (LNG) … See more • Approximate chemical formula: ((K2O)2⁄3 (Na2O)1⁄3) • Al2O3• 2 SiO2 • 9/2 H2O • Silica-alumina ratio: SiO2/ Al2O3≈2 See more • Chemical formula: 0.7CaO•0.30Na2O•Al2O3•2.0SiO2 •4.5H2O • Silica-alumina ratio: SiO2/ Al2O3≈2 Production 5A molecular sieves are produced by cation exchange of See more
