Molecular Sieves

MoIca, are synthetic zeolites (crystalline metal alumina-silicates) with small & uniform pores, having precisely defined diameter of molecular dimensions. Molecular Sieves of highest quality are our forte. Producing molecular sieve desiccant, molecular sieve beads, Air drying molecular sieve, SF6 molecular sieve, Molecular sieve for Oxygen plant. 

Selectivity of molecular sieve is determined by its pore size. They comprise a mesh of cavities and narrow pores and a very high internal surface area.

Molecules with critical diameter less than the pore size will be efficiently adsorbed while larger molecules will be excluded.

Most important characteristic of molecular sieve is to perform reversible adsorption of various gaseous compounds.

These crystals are characterised by a three dimensional pore system. The corresponding Building Blocks of Molecular Sieve crystallographic structure is

tetrahedral where four oxygen anions surrounding a silicon or aluminium cation (AlO4) and (Sio4).

They are the basic building block for various zeolites which are the most common commercial adsorbents. Molecular sieves are the only adsorbents that remain

effective under very hot conditions and can bring down dew point levels to -60 deg. And work at as low relative humidity as 10-20%.

Molecular Sieves are the most diversified range of adsorbents used in petroleum, petrochemical, fertilizer and industrial chemical process industry.

CARMOS Carbon Molecular Sieve is a carbon enriched

Molecular Zeolite CMS is a 4 angstrom fine pore

adsorbent. It can be used to separate air into nitrogen and

oxygen. In industry, CMS can concentrate nitrogen from air

with PSA systems. It can meet the requirement of all types

of PSA nitrogen systems. The carbon molecular sieve is

widely applied in petro-chem industry, heat treatment of

metal, electronic manufacturing and food preservation and

packaging industries. (1.0-1.5 mm pellets with crushing b
