Molecular sieve 4A is suitable for the drying of gas and liquid, with a aperture of about 4 angstroms. It adsorbs such gases as H2O, NH3, H2S, CO2, SO2, CO, H3CCl, H3CBr, H2C2 ,H6C2, H4C2,H6C3. It is widely used in the drying of natural gases. It is also widely used in dehydration of ethanol and anti-dewing for insulating glass, etc. Application of Molecular sieve 4A: Air, natural gas adsorption, for desulfurize, carbon dioxide removal. Make and depurate Argon gas. Electric component and aquosity substance. Oil paint, polyester, dye dehydration.
