Zeolite Molecular Sieves

Zeolite molecular sieves are crystalline structures with a solid framework defining large internal cavities where molecules can be adsorbed. Because of their crystalline nature, the pores and cavities are all precisely the same size, and depending on the size of the openings, they can adsorb molecules readily, slowly, or not at all, thus functioning as molecular sieves – adsorbing molecules of certain sizes while rejecting larger ones.

Zeolites also act as catalysts, or promoters of specific chemical reactions. The catalytic properties of zeolites can be customized by selecting the appropriate pore size and shape, and exchanging the silica and alumina atoms in the structure with other metal ions, e.g. Ba, Fe, Ti, and Zn.

The following is a list of the basic types of molecular sieves that UOP can offer your company. These zeolites are available as powders, or bound with clay or alumina supports. Our Specialty Products group can customize these products through both ion exchange and forming of their basic materials.
