Aluminosilicate compound having a cubic lattice, the alumina is mainly
composed of the open connection through an oxygen bridge skeleton
structure, there are a lot of uniform pore size and pore structure grace molecular sieves are
arranged neatly, the inner surface area of a large hole. Also
contains a lower price and ionic radius larger metal ions and compounds
of state water. As water molecules in the continuous loss of heat, molecular sieve manufacturers but
the same crystal framework structure, the formation of many of the same
size of the cavity, the cavity of the same diameter,molecular sieve
drying, there are many pores are connected, the diameter of these small
pores of uniform size, pore ratio can adsorption of molecules having a
small diameter into the interior cavities in the regeneration of molecular sieves past,
but have the molecules larger than the pore exclusion, different shapes
can thus molecular diameters, different degrees of polarity of the
molecule, molecules having different boiling points and different degree
of saturation of molecular separation open, that has the effect of
"screening" of molecules, so called molecular sieves. Currently zeolite
widely used in metallurgy, chemical industry, electronics, petrochemical
and natural gas industries.
