产品说明

一般描述

Molecular sieves are crystalline, synthetic zeolites. Their crystal gratings are similar to a cage with numerous hollow spaces. The cavities are accessible from all sides by pores of exactly defined dimensions. Molecular sieves can be generally used in desiccators and drying tubes; for keeping absolute solvents dry; for drying gases or solvents in drying columns.

应用

Molecular Sieve 13X is a highly porous sodium form of zeolite X that is widely used in the purification of air before liquefaction, natural gas purification, separation of substances, and drying. It is also suitable for the adsorption of large molecules such as aromatics, branched-chain hydrocarbons, and organosulfur compounds. Molecular Sieve 13X has a greater ability to accept molecules because of its higher SiO₂/Al₂O₅ ratio. Therefore, 13X also finds the application in the removal of phenolic pollutants.

产品说明

一般描述

选择分子筛：
1.一个分子相对另一个分子优先吸附主要取决于孔径和网眼尺寸。
2.硅胶吸附特定化合物的动态能力取决于内表面积；表面积越大，动态容量越大。
3.吸附速率和分辨率锐度主要取决于粒径和柱填充物；细小颗粒可使分辨率达到最佳的锐度。
4.液体最容易从溶解性最低的溶剂中被吸附出来；好的溶剂则可成为好的解吸剂。
5.高极性液体容易被吸附。具有羟基或含氧的化合物可被强烈吸附。
6.对于类似的化合物，分子量越大，选择性越高。
7.对于分子量相近的碳氢化合物，吸附性能随双键数的增加而增加。

再生或活化：
饱和分子筛可以通过再生恢复到原来的容量，其原理涉及改变吸附剂周围的条件，以对应非常低的平衡容量。一般来说，吸附和再生的平衡能力相差越大，再生越迅速和完全。
分子筛可以通过以下四种方式之一进行再生：
1.加热再活化 - 二氧化硅的最高再生温度为 300℃。
2.压力再活化
3.在常温常压下，使用恰当的液体通过凝胶床。
4.将高浓度分子溶于流体中，并通过过床层，从而带走吸附物。

一般描述

Choosing a Molecular Sieve:
1. The preferential adsorption of one molecule over another depends upon pore diameter and mesh size.
2. The dynamic capacity of the silica gel for adsorbing a particular compound is governed by the internal surface area; the greater the surface area, the greater the dynamic capacity.
3. Rate of adsorption and sharpness of resolution are dependent chiefly on particle size and column packing; a fine particle size gives optimum sharpness of resolution.
4. Liquids are most readily adsorbed from solvents in which they are least soluble; a good solvent makes a good desorbing agent.
5. Highly polar liquids are readily adsorbed. Compounds having hydroxyl groups, or containing oxygen are strongly adsorbed.
6. For similar compounds, the higher the molecular weight the higher the selectivity.
7. For hydrocarbons of similar molecular weight, adsorptivity increases with the number of double bonds.
Regeneration or Activation:
A saturated molecular sieve can be restored to its original capacity by regeneration, the principle of which involves changing the conditions surrounding the adsorbent to correspond to a very low equilibrium capacity. In general, the greater the difference between the equilibrium capacities of adsorption and regeneration, the more rapid and complete the regeneration.
The sieve may be regenerated in one of four ways:
1. Thermal reactivation –The maximum regeneration temperature for Silica is 300℃.
2. Pressure reactivation
3. Passing an appropriate fluid through the gel bed at normal temperature and pressure.
4. Displacement of adsorbates by passing a high concentration of molecules in a fluid through the bed.
