Air gas drying zeolite

Small Molecular Sieve Sphere Beads

Product Overview

BASF Molecular Sieve products are zeolitic materials based on synthetic aluminosilicates. These are produced to be spherical and with a regular, defined, porosity measured on the Ångström length scale. This controlled pore size allows for selective adsorption based on molecular size.

Typical applications are the drying of technical gases and polar liquids. This is due to the high adsorption capacity for polar compounds.
