Molecular Sieves
    The Molecular Sieves is a kind of Aluminosilicate. With the character of pore size and much more specific surface, it has much excellent merit as following:

  1. The selective absorption, according to the size and shape of absorbed molecule, it can absorb only those molecules whose diameter are less than the molecular sieve pore.
  2. It has the selective absorption for the polar or unsaturated molecules. The higher the polarity or unsaturated, the selective absorption is stronger.
  3. It has strong water absorption. Even if higher temperature, larger flow rate and lower water content. It keeps still higher water absorption.
