Molecular Sieves

Molecular sieves have a wide variety of uses in gas and chemical purification processes. We offer Types 3A, 4A, 5A, and 13X beads in a variety of mesh sizes in the standard container sizes shown below. Custom packaging is also available.

Beads Offer Distinct Advantages Over Pellets

• Beads provide a greater surface area per cubic foot resulting in more efficient adsorption for equivalent sized beds.
• Beads are stronger than pellets, thus they maintain their size and shape for more efficient adsorption.
• Beads do not create dust to the degree that pellets do; this results in a cleaner system with less frequent clogging of system filters.
• Beads offer an equivalent pressure drop to pellets.

Molecular Sieve 3A-Formula K12[(AlO2)12.X H2O

The potassium form of the Type A Crystal structure, is an alkalai metal alumino-silicate. Type 3A is used for drying polar liquids such as ethanol and methanol and the dehydration of unsaturated hydrocarbons such as acetylene, butadiene, and propylene.

Molecular Sieve 4A-Formula Na12[(AlO2)12.X H2O

The sodium form of the Type A Crystal structure, is an alkalai metal alumino-silicate. Type 4A is used for drying inert gases and saturated hydrocarbons, such as methane, ethane, and propane.

Molecular Sieve 5A-Formula Ca4,5Na3[(AlO2)12.X H2O

The calcium form of the Type A Crystal structure is an alkalai metal alumino-silicate. Type 5A is used for separating normal paraffins from branched-chain and cylic hydrocarbons through selective adsorption process.

Molecular Sieve 13X- Formula Na86[(AlO2)86(SiO2)106].X H2O

The sodium form of the Type X Crystal structure, is an alkalai metal alumino-silicate. Type 13X is used for general drying of inert gases and saturated hydrocarbons, purification of air through removal of water and carbon dioxide, and the removal of H2S and mercaptans from natural gas.
