1 DESCRIPTION4A MOLSIV Adsorbent is a clay-bound sodium form ofType A molecular sieve . 4A molecular sieve will adsorbmolecules with critical diameters up to 4 angstroms. Itadsorbs water and ethanol, but not larger molecules molecular sieve is recommended for the dehydrationof air in hopper (plastic) drying units and pressureswing (PSA) dehydrators. Its exceptional productstrength makes 4A ideal for sachet and other custompackaged desiccating [(AlO2)x(SiO2)y] z H2O [M=Na]REGENERATION4A molecular sieve can be regenerated for re-use bypurging or evacuating at elevated temperatures. Thedegree of regeneration is dependent on the temperatureand humidity of the purge ANDSAFEHANDLINGSee the UOP brochure Precautions and Safe Practicesfor Handling molecular Sieves in Process Units or callyour UOP is shipped in steel drums or Quick-Load MOLSIVTMADSORBENTUOPTMADSORBENTS14 x3010x208x124x81/16 1/8 granularBeadsBeadsBeadsPelletsPelletsNom inal Pore Diameter (angstroms)4 4 4 4 4 4 Particle Size Diameter (mm) Density (lbs/ft3)
