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 5 angstroms.
Applications：Used for the dehydration and purification of various hydrocarbon and
non-hydrocarbon gas and liquid streams. It is used for the separation of
straight and branched chain hydrocarbons, sweetening and drying of natural
gases and the production of high purity hydrogen.
