Molecular Sieve 5a For Separation Of Normal And Iso-paraffins
5A molecular sieve is a highly efficient adsorbent, mainly used for the adsorption separation of normal and isoparaffins. Its pore size is about 0.5nm, which can effectively adsorb normal paraffins with a kinetic diameter smaller than its pore size, and can also adsorb isoparaffins with a kinetic diameter larger than its pore size, thereby achieving the separation of normal and isoparaffins.
The application of 5A molecular sieve in the separation of normal and isoparaffins is mainly reflected in the following aspects:
Adsorption separation of normal and isoparaffins: The pore size of 5A molecular sieve is between the kinetic diameters of normal and isoparaffins, which enables it to selectively adsorb normal paraffins, thereby improving the purity of normal paraffins, which is of great significance in the production of chemical products such as surfactants and synthetic detergents.
Improve refining efficiency: In the paraffin industry, 5A molecular sieve is used for the separation of normal and isoparaffins, such as C4-C6 fractions, which can improve refining efficiency.
