Use 5A molecular sieve to adsorb and separate the recombinant components in mineral oil to obtain high-purity n-hexane. The results of studying the effects of adsorption temperature and space velocity on the adsorption of molecular sieves from different manufacturers show that 5A molecular sieve has a strong adsorption effect on n-hexane in the recombinant component of mineral oil, and has a strong saturation adsorption capacity.

When the adsorption temperature is 80 ℃and the adsorption space velocity is 3h-1, the adsorption effect is good. At this time, the content of normal paraffins in molecular sieves decreases significantly, and the content of isoparaffins remains unchanged. The amount depends on the moisture content in the product.

Molecular sieve has a large adsorption capacity, and the general adsorption capacity is 22%。

1. Uses: Molecular sieves have selective adsorption and can remove organic solvents and gases in gases, but cannot remove solvents and gases. For example, the initial dehydration method of tetrahydrofuran is to use caustic soda to remove it. Caustic soda is soluble in water. After dehydration, it is difficult to After separating from tetrahydrofuran and using caustic soda, it is difficult to recycle and the cost will inevitably increase

2. Operation: The dehydration operation of molecular sieve is relatively simple. The molecular sieve can be directly put into the solution or directly made into a solution, so that the gas flows into the sieve adsorption tower.

3. Adsorption capacity: Molecular sieve has a large adsorption capacity, and the general adsorption capacity is 22%.

4. Adsorption: Molecular sieves are easy to adsorb polar water molecules. Because the diameter of water molecules is smaller than the pore size of molecular sieves, water molecules and molecular sieves can reach electrostatic equilibrium after adsorption (molecular sieves do not adsorb larger than the diameter of the pore size). The entire adsorption process is a physical reaction. The removed substance does not undergo any chemical reaction

5. Anhydrous analysis: After the molecular sieve absorbs water, it does not release the absorbed water at room temperature

6. Regeneration: The regeneration of molecular sieve is relatively simple. The molecular sieve drum is more than 300 nitrogen, and the molecular sieve can be used again after 1 hour.

7.long lifetime: Molecular sieves can usually be recycled for 3-5 years.

The above is the manufacturer's introduction on the dehydration use and regeneration of 5A molecular sieve. According to the introduction, you can understand and use this product more clearly, so that its performance can be fully utilized.
