Introduction

Molecular sieve, also known as zeolite, has many pores with uniform pore size and orderly arranged holes in structure;Molecular sieves with different pore sizes separate molecules of different sizes and shapes, lt has high adsorption capacity, strong selectivity and high temperature resistance.

Application

Molecular sieves are widely used in adsorption purification,.dehydration drying and catalysis in organic chemical and petrochemical industries.
