Attention:
•The product as desiccant cannot be exposed in the open air and should be stored in dry
condition with air-proof package.
•The product should be regenerated after a certain period of adsorption. the appropriate regenerated temperature would be better below 350℃.
Description: A kind of alkali-metallic, silicon-aluminum compounds, It could absorb the
molecular which critical diameter is not more than 4 angstroms.
Applications：lt is mainly used for desiccation of gases and liquids ,such as associated gas in
oil field and natural gas, adsorbing H20, H2S, NH3, SO2, CO2,C2H5OH,C2H6 and so on
