When selecting a molecular sieve, many people focus on its pore size and material, but often overlook the impact of particle size on adsorption capacity. In fact, particle size directly relates to filtration area and adsorption efficiency, and it also needs to be matched with usage conditions like temperature and pH. This article will explain the relationship between molecular sieve size and adsorption capacity, introduce key factors affecting adsorption, and recommend suitable products to help you make the right choice.
Basic Functions and Advantages of Xintao Molecular Sieve
Molecular sieves are porous structures that can adsorb any molecule smaller than the pore size. It is mainly used for the separation of normal isomers and, pressure swing adsorption and co-adsorption of water and carbon dioxide. Choose Xintao molecular sieve adsorbent, which has fast adsorption speed and is especially suitable for pressure swing adsorption. It can adapt to various specifications of oxygen production, hydrogen production, carbon dioxide and other gas pressure swing adsorption equipment. It is a boutique in the pressure swing adsorption industry.
How Molecular Sieve Size Influences Adsorption Capacity?
The size of the molecular sieve particles also has an effect on the adsorption capacity. Generally, the smaller the molecular sieve particles, the larger the filtration area. Therefore, granular molecular sieves have a large surface area and the best adsorption efficiency. Due to the formation of particles, the granular molecular sieve is not easy to flow, and it also makes it difficult for impurities such as organic matter in the filter medium to be blocked in the molecular sieve filter layer, with strong adsorption capacity and more convenient replacement.
Other Key Factors Affecting Molecular Sieve Adsorption Capacity
The adsorption capacity of molecular sieve desiccant is related to the ambient temperature. The higher the temperature, the stronger the adsorption capacity of the molecular sieve. If the adsorption ambient temperature is higher than 300°C, the adsorption capacity reaches the limit and the adsorption capacity will gradually decrease. The adsorption capacity of molecular sieve is proportional to the contact time of gas and liquid, the longer the contact time, the higher the purity of gas and liquid after filtration. When the adsorption environment is acidic, the adsorption capacity of molecular sieves for anionic substances is relatively weakened; when the adsorption environment is alkaline, the adsorption capacity of molecular sieves for cationic substances is weakened. Therefore, the pH of water is unstable, which also affects the adsorption capacity of molecular sieves
