Activation Method of 4A Molecular Sieve

4A molecular sieve has a wide range of applications. It is not only a new type of high-performance microporous adsorbent, but also a catalyst carrier with excellent performance. As a desiccant, molecular sieve has strong drying efficiency and can be used to dry a variety of gases and liquids. Activating molecular sieves cannot be used to dry unsaturated compounds because they have a strong adsorption effect on unsaturated molecules, polar molecules and easily polarized molecules. Molecular sieve has a small water absorption capacity. If the material to be dried contains too much water, it should be dehydrated with other desiccants first, and then dried with molecular sieve.
