Method and apparatus using molecular sieves for freeze

30 07 1991Recently I have discovered that molecular sieves can be placed in long open mesh columns while at the same time significantly improving the adsorption and desorption functions of the sieves in freeze drying For example 40 grams of Type 3A sieve placed within an open aluminum mesh column held within a 62 solid wall copper tube satisfactorily adsorbed 4 4 grams of sublimating

MOLECULAR SIEVE 3A

The discovery of the molecular sieve was in 1756 when the term zeolite was used for the first time to describe a solid material of which the part of water could be removed by heating The term molecular sieve has its origin JW McBain and defines a porous solid material that has the property to act as a sieve at the molecular level This is a class of adsorbent which has the ability to retain
