    Application fields and development prospects of microporous molecular sieves Application fields and development prospects of microporous molecular sievesFor half a century, molecular sieves have played an increasingly important role in petroleum processing, petrochemical and fine chemicals, and environmental chemicals as the main catalytic materials, adsorption separation materials and ion exchange materials. Nevertheless, the role of molecular sieves in the above three traditional fields still has great prospects for development. First, there are 213 molecular sieves with known structures so far (2013). Look, there is still a lot of room for development. However, so far, only A, X and Y faujasite, mordenite, ZSM-5, ZSM-11, MCM-22, L, B, erionite, RHO, CHA have been used on an industrial scale. , AEL type and TS, and less than twenty kinds of SAPO-34, SAPO-11, SAPO-31 and so on.ZSM-5 molecular sieveIt is speculated that in the next two decades, due to the need for the development of fine chemicals and intermediate chemicals, as well as the renewal and developme...

    Application of activated alumina and molecular sieve Both activated alumina and molecular sieves are solid materials with internal hollow pore structure, which have the characteristics of large specific surface area and adjustable pore size. Both have good adsorption capacity and are commonly used adsorbents in industrial production. Then we will use an article to introduce the application of activated alumina and molecular sieve.First, the application of activated aluminaActivated alumina (γ-Al2O3) is a solid material with high porosity and high dispersity. It has the characteristics of large surface area, good adsorption performance, surface acidity and good thermal stability. Activated alumina belongs to transition form alumina. For powder, spherical or columnar white solid. Its crystal structure is different from that of industrial alumina. Activated alumina belongs to the tetragonal crystal system, and the structure of the lattice is very similar to that of spinel. The crystal of activated alumina is disordered. This disorder...

    The difference between activated alumina and molecular sieve Both activated alumina and molecular sieves are commonly used adsorbents in industrial production, and both play an irreplaceable role. But there is a question that has been entangled with us, that is, what is the difference between activated alumina and molecular sieve? What are the different effects. Knowing this, I can make rational product choices in industrial production. So today I focus on analyzing their specific differences from the perspective of structure, adsorption performance, and application.First, the difference in structureBoth activated alumina and molecular sieve are solid materials with high porosity and high dispersion, and both have a large specific surface area, but the difference between activated alumina and molecular sieve can be seen from the distribution of structural pores. Molecular formula of activated alumina: Al2O3 -x(OH)2x, 0<x<0.8. The pore structure distribution of activated alumina is relatively messy, and is generally divided into micropo...

    Three Importances of Medical Molecular Sieve Oxygen System The medical molecular sieve oxygen production system uses zeolite molecular sieve as the adsorbent, and uses pressure swing adsorption (SPA) to produce medical oxygen equipment (referred to as oxygen generator). The equipment uses air as raw material under normal temperature and low pressure, and directly separates it by physical methods, thereby improving the purity of medical oxygen.The principle of medical molecular sieve oxygen production: The core component of the oxygen production system is the oxygen-producing molecular sieve. The molecular sieve is a semi-permanent adsorbent molecular sieve with zeolite as the main raw material. It can enter the cavity through the orifice of the micropore, adsorb on the surface of the cavity, and desorb and release under certain conditions, and molecules larger than the pore size cannot enter, thereby effectively separating nitrogen and oxygen. Oxygen can be sent to various hospitals for use through oxygen storage tanks.The principle of medical...
