The pore size for molecular sieve is about 5Ao. It can adsorb all kinds of molecular smaller than this size, it is mainly used in separation of the normal and isomerous alkane,pressure swing adsorption (PSA) for gases,co-adsorption of moisture and carbon dioxide. Based on the industrial application specialities, we have produced out our own PSA molecular sieve products, which have better selective adsorb ability and more rapid adsorption speed, being the elaborated products, it could suitable for gases generation and concentration PSA plants of any sizes and any types in the world.
