  Instead, those molecules are absorbed by the sieve. The empty spaces in the sieves structure, the pores, hold those smaller molecules, so a sieve's effectiveness not only depends on the size of the pores but on how much empty space is available inside the sieve's structure. Molecular sieves can absorb about 24 percent of their weight. Guidelines for Mastering the Properties of Molecular Sieves that these solids exhibit as a characteristic feature and which explains the term of "molecular sieves" currently used to name these ma­ terials. Indeed, a large number of industrial processes for separation of gases and liquids, and for catalysis are based upon the use of this.

Molecular sieve, a porous solid, usually a synthetic or a natural zeolite, that separates particles of molecular es are hydrated metal aluminosilicate compounds with well-defined crystalline structures. The silicate and aluminate groupings form three-dimensional crystal lattices surrounding cavities in which the metal ions and the water molecules are loosely held. 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 a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight.

Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. 1 Molecular Sieve Zeolites II. Molecular Sieve 5A and 13X are referred to as zeolite molecular sieves. These crystalline materials are synthetically produced and have very uniform internal cavities. I am not going to discuss structural/composition details of Molecular Sieve type A materials verses Molecular Sieve type X materials, but rather focus on helping new analysts.

Molecular Sieves and Zeolites Molecular sieves are porous solids with pores of the size of molecular dimen-sions, – nm in diameter. Examples include zeolites, carbons, glasses and oxides. Some are crystalline with a uniform pore size delineated by their crystal structure, for example, zeolites.

Energy & Fuels27 (8), Cited by: Molecular sieves (zeolites) are artificially prepared alkali metal aluminosilicates. The most common types used for gas chromatography are type 5A, a calcium aluminosilicate with an effective pore diameter of nm, and type 13X, a sodium aluminosilicate with an effective pore diameter of 1 nm.

Corma has written about articles on these subjects in international journals, three books, and a number of reviews and book chapters.

Molecular sieves are crystalline metal aluminosilicates having a threedimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size.
