Molecular sieve is a material of crystalline metal aluminosilicates which having an interconnecting network of zeolite and alumina tetrahedra. Molecular sieve is used as a desiccant and adsorbents. It More
Molecular Sieves are used to purify the gas streams & as absorbents to remove the water or decrease the humidity. in our blog post, we are focused on what are the things we need to know while purchasing absorbents.
How a Molecular Sieve Works
The material used in an industrial molecular sieve has small uniform pores. When other substances come in contact with the molecular sieve, the molecules that are the right size to fit in the pores will be adsorbed. The molecules that are too large to fit will not. Molecular sieves function at the microscopic level; therefore their sizes are measured in angstroms. Pore sizes 3Å and 4Å will adsorb water while larges sizes remove larger hydrocarbons.
Molecular Sieve using raw Materials
In a strictly scientific sense, many regular desiccant dehumidifiers like lime, clay and silica gel also work by filtering molecules of water vapour, but marketable molecular sieves are made of synthetic crystalline alumina silicates. Unlike absorbents found in nature, the mechanism of pore size during manufacture produces selective adsorption characteristics.
The Benefits of Molecular Sieves
Molecular Sieves adsorbents usually adsorb the water much quicker than other adsorbents & same they can decrease the humidity to much lower level that the standard silica gel. they are also more effective than natural adsorbents for applications that exceed normal room temperature, when correctly used they can be effective in reducing water molecules as low as 1ppm in specialized containers or to 10% comparative humidity in packaging
