What Are the Applications of Molecular Sieve in Petrochemical Industry? In the more than half a century since the advent of molecular sieves, the technologies have been mainly used to meet the needs of three traditional fields, first of all, in the catalytic process of traditional petroleum and chemical industry, then in the ion exchange process required for the treatment of waste gas and waste liquid in the daily necessities industry, coal mines and radioactive industries, and so on. The application of molecular sieves in the petrochemical field continues to expand, which promotes the rapid development of the national economy.…

Method for Strengthening Performance of Molecular Sieve Molecular sieves are materials with uniformly sized pores (very small pores). The size of these pores is similar to the size of small chemical molecules. Therefore, large molecules cannot enter the molecular sieve or be adsorbed, while small molecules can. As a mixture of molecules migrates and passes through a fixed bed of porous semisolid matter that is called a sieve (or matrix), the components with the highest molecular weight (which cannot enter the molecular pores) leave the bed first and then are followed by sequentially smaller molecules. Some molecular sieves are used…

4A Molecular Sieve Can Be Used As a Molding Agent for Soap The pore size of 4A molecular sieve is 4A, which can adsorb any molecule with a diameter smaller than 4A. The factors that affect the actual performance of 4A molecular sieve generally include air flow, air temperature, air quality, air flow rate, purifier design, and purifier bed height and diameter than wait. 1. Precautions for the operation of 4A molecular sieve 4A molecular sieve should pay attention to the packaging of 4A molecular sieve during operation. Since 4A molecular sieve is very easy to absorb moisture in the…

What Are Characteristics of the 4A Molecular Sieve? Due to the large pore structure and particle size of 4A molecular sieve crystals, the adsorption performance of the 4A molecular sieve is very strong. For the adsorption of non-ionic surfactants, 4A molecular sieve is 3 times that of NTA (secondary aminotriacetate) and sodium carbonate, and 5 times that of sodium tripolyphosphate (STPP) and sodium sulfate, so this property is used for agglomeration molding. It would make sense to produce more concentrated surfactants in high strength detergents to produce products with good wash and flow properties. 1. The 4A molecular sieve has…

The Shape and Performance of Solid Adsorbent of Activated Alumina 1. Shape and performance of activated alumina Solid adsorbents are used in reactors with different particle shapes. Early adsorbents did not pay attention to the shape, and often only crushed the bulk material, and then screened out the particles with uneven particle size and irregular shape for use. Due to the indeterminate shape, the airflow distribution during use is very uneven, and the adsorption reaction is affected. The sieved small particles and powder materials cannot be used and discarded, thus causing a lot of waste. With the continuous improvement of…

How To Activate Molecular Sieve? Why Do You Need to Activate a Molecular Sieve? In the process of storage and transportation, a molecular sieve will absorb a small amount of water and carbon dioxide. Activation can ensure molecular sieve maximum adsorption capacity. For a molecular sieve, activation means emptying the adsorbent to expose the surface, which can affect the adsorb of the reaction materials and shorten the reaction induction period. What is a Molecular Sieve? Molecular sieves adsorb different substances by their adsorption priority and aperture. It is an aluminosilicate microporous crystal. Molecular sieves have four major uses and various…

Activated Alumina Ball Plays an Important Role As a Desiccant Dehydration is a widespread need in industry, and the presence of moisture often negatively affects the production process. Therefore, for most production environments under non-vacuum conditions, drying the air is the first step to ensure smooth production. In current industrial production, compressed air is an important source of power. As it is widely used, drying equipment for removing water vapor in compressed air has also been developed and applied accordingly. Among them, the heatless regeneration adsorption compressed air dryer has the advantages of simple structure, low power consumption, low investment,…

Factors Affecting the Adsorption Performance of Activated Alumina Activated alumina is generally prepared by heating and dehydrating aluminum hydroxide. Aluminum hydroxide is also called hydrated alumina. Its chemical composition is Al2O3·nH2O. Usually, it can be divided into alumina trihydrate and alumina monohydrate according to the number of crystal water contained. After heating and dehydration of aluminum hydroxide, γ-Al2O3 can be obtained. That is commonly referred to as activated alumina. 1. Use of activated alumina Activated alumina belongs to the category of chemical alumina, and activated alumina is used for adsorbents, water purifiers, catalysts and catalyst carriers. Activated alumina has selective…
