Exprience the highest adsorption yeild by PETROTAT Molecular Sieves
Molecular sieves come in different types such as 3A, 4A, 5A and 13X. The numeric values define the size of the pore and the chemical composition of the sieve. The ions of potassium, sodium, and calcium are altered in the composition to control the size of the pore. There are different numbers of meshes in different sieves. A molecular sieve with a smaller number of meshes is used to separate gases, and one with more meshes is used for liquids. Other important parameters of molecular sieves include the form (powder or bead), bulk density, pH levels, regeneration temperatures (activation), moisture, etc.

Examining the physical characteristics of the Molecular Sieve
One of the important characteristics of Molecular Sieve is its internal and three-dimensional alumino-silicate structure. This structure is in the form of regular holes and uniform porosity, and these structural characteristics increase the selectivity of the adsorbent and create high absorption and separation power.
Examining the physical characteristics of the Molecular Sieve
The crystal structure of Molecular zeolite creates selectivity in it. This structure is connected by channels and holes with specific and uniform dimensions. Therefore, the molecular absorption method is such that the molecules that have suitable dimensions and size compared to the size of the channels and cavities can enter the surface of the inner cavity and be absorbed.That is, during the passage of liquid and gas, the molecular barrier allows the passage of larger particles and absorbs smaller particles.Consequently, the ability to separate molecules is due to these same pores and channels. But we must know that when the molecular ratio reaches saturation, the regeneration process must begin. This process is associated with the heating of the Molecular Sieve at a temperature of 130 to 250 degrees Celsius.
