5A Molecular Sieve

5A Molecular Sieve

Description:
The 5A molecular sieve sometimes also called calcium molecular sieve or 5A zeolite, is often utilized in the petroleum industry, especially for the purification of gas streams and in the chemistry laboratory for separating compounds and drying reaction starting materials.

It contains tiny pores of a precise and uniform size, and it is mainly used as an adsorbent for gases and liquids.

This sieve operates on molecular level and traps absorbed substances. It can adsorb water as much as 22% of its own weight. Its adsorption principle is quite similar to that of size exclusion chromatography, except that without a changing solution composition.

Capable of pressure swing adsorption (PSA), the 5A molecular sieve is widely used in variable pressure swing absorption (PSA) devices. It can absorb different gases, such as C3-C14, C2H5CL, C2H5Br, CH3L, C2H5NH2, CH2CL2CH2Br2, CHF2CL, CHF3, CF4, (CH3)NH2, B2H6CF2CL2, CHFCL2, and CF3CL, etc.

Regarding the delivery period of calcium molecular sieve, 12days/20gp is for those to be exported abroad, and 7days/20gp is for the ones sold at home.

The selective adsorption capacity and speed of this 5A zeolite are much better than that of 3A and 4A molecular sieves.

Formula: 0.7CaO•0.30Na2O•Al2O3•2.0SiO2 •4.5H2O

Applications:
1. The 5A molecular sieve can be applied in normal paraffin separation;
2. This kind of sieve is also used in separating oxygen and hydrogen gases.
3. 5A zeolite can be utilized in drying and refining various gases and liquids.

Storage:
1.The 5A molecular sieve should be preserved under room temperature.
2.Water, acid and alkali ought to be avoided.
3.Air isolation is necessary for this calcium molecular sieve.
