Product description
Molecular sieve is a material containing tiny pores of a precise and uniform size .
Molecular sieves are often utilized in the industry, especially for the purification of gas streams and
in the chemistry laboratory for separating compounds and drying reaction starting materials.
The content is extremely harmful to the aluminium piping and other parts of the liquefaction
apparatus is used in this case.
Methods for regeneration of molecular sieves include pressure change (as in oxygen concentrators),
heating and purging with a carrier gas (as when used in dehydration), or heating under high vacuum.
3A (pore size 3 Å): Adsorbs NH3, H2O, (not C2H6), good for drying polar liquids.
4A (pore size 4 Å): Adsorbs H2O, CO2, SO2, H2S, C2H4, C2H6, C3H6, EtOH. Will not adsorb C3H8 and
higher hydrocarbons. Good for drying nonpolar liquids and gases.
5A (pore size 5 Å): Adsorbs normal (linear) hydrocarbons to nC4H10, alcohols to C4H9OH, mercaptans to C4H9SH. Will not adsorb isocompounds or rings greater
than C4.
13X (pore size 10 Å): Adsorbs (not tri-n-butylamine). Useful for drying .
