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.

Zeolites and related crystalline molecular sieves can possess catalytically active acid sites, as well as uniformly sized and shaped pores and voids, that Cited by: A molecular sieve is a material with pores 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 substance referred to as a sieve, the components of highest molecular weight leave the bed first, followed by successively smaller molecules. Some molecular. By `molecular sieve` is meant herein microporous three dimensional framework materials having pores generally in the 2 to 20 Angstroms size range which are capable of use for molecular separations.

Polyoxometalate (POM) catalysts with different trivalent hetero ions (Mn+ = Fe3+, Al3+, and Cr3+) were prepared by incipient wetness impregnation method and supported on different zeolites namely, NaY, ZSM-5 and Mordenite.

The intended catalysts samples were distinguished by X-ray diffraction, FTIR and surface texture measurements. The data given disintegration in the crystallinity of zeolite Author: Mohamed S. Thabet. Some effort was devoted to the development of zeolite materials with larger pores (> nm),1,2 but the increases in pore size were modest.

Further, these new materials are not very effective in reactions with large-sized molecules or for petroleum cracking reactions.2 The.
