The principle of pressure swing adsorption is a material separation, purification and purification method based on molecular power difference, which can be widely used in chemical industry, biomedicine, food, environmental protection and other fields. The basic principle of

1. pressure swing adsorption principle

pressure swing adsorption technology is to adjust the pore size of the adsorbent by changing the physical characteristics of isothermal adsorption of gas in the adsorbent, so that the adsorbate molecules are gradually adsorbed and separated from coarse pores to fine pores according to the size of the power difference, so as to achieve the purpose of separating and purifying substances. The basic principle is: an adsorption layer will be formed on the surface of the solid. When the gas passes through the solid, due to the synergistic effect, a certain degree of adsorption will occur, thereby increasing the concentration of the substance. The higher the concentration of the substance can be followed up, so as to achieve The purpose of purification and purification. The application fields of

2. pressure swing adsorption principle

1. Chemical industry: pressure swing adsorption can be used for catalyst preparation, purification of various organic substances, adsorption and treatment of environmental pollutants, etc.

2. Biomedicine: It can be used for the preparation and separation of biomolecules such as oligopeptides and peptide compounds, the purification of raw materials or crude drug liquids, and the separation and purification of drug raw materials;

3, food field: pressure swing adsorption can be used for food processing and extraction, such as: fruit juice, food pigment and quality regulators, such as separation and purification;

4, environmental protection field: pressure swing adsorption is an effective method to deal with VOCs, air pollutants, water pollutants, etc.

the advantages of 3. pressure swing adsorption principle

1. No separation liquid is required, which is very suitable for the separation and preparation of organic substances and aqueous solutions;

2. Because the separation process does not need to cooperate with high temperature, high pressure, etc., it has obvious advantages for the separation of macromolecular compounds and proteins;

3. Strong controllability and screening, easy to achieve accurate control of separated substances.

4. how to further promote the pressure swing adsorption

Because the pressure swing adsorption principle is widely used, but its development still has various problems, such as adsorbent selection, adsorbent fluctuation, poor selectivity and so on. Therefore, for researchers and developers engaged in the field of pressure swing adsorption, it is necessary to analyze and solve various problems in depth in order to promote the development of pressure swing adsorption technology.

pressure swing adsorption principle as a high-performance material separation, purification and purification method, has been widely used in industrial and biomedical fields. For researchers engaged in related fields, we should have an in-depth understanding of the principle of pressure swing adsorption, and in-depth exploration of the optimization and development of technology to achieve more efficient and accurate material separation and purification effects.
