4A Molecular Sieve Can Be Adsorbed According to the Size of the Molecule

4A Molecular Sieve Can Be Adsorbed According to the Size of the Molecule As we all know, the structural characteristics of 4A molecular sieve determine its good adsorption performance, catalytic performance and ion exchange performance. Where are these three performances mainly manifested? 1. Performance characteristics of 4A molecular sieve Adsorption performance: The pore size of 4A molecular sieve is average, and when the dynamic diameter of the molecule is smaller than the pore size of the molecular sieve, it can enter the inside of the channel for adsorption. 4A molecular sieve is like a sieve that separates gas and liquid.…

Why Only Molecular Sieve 3A is Qualified to Be Used in Hollow Glass?

Why Only Molecular Sieve 3A is Qualified to Be Used in Hollow Glass? Molecular sieve can simultaneously adsorb water and residual organic matter in the hollow glass, so that the hollow glass remains clean and transparent even at very low temperatures. At the same time, it can fully reduce the strong internal and external pressure difference of hollow glass caused by the huge temperature difference between seasons and day and night. The molecular sieve in the hollow glass also solves the problem of distortion and breakage caused by expansion or contraction, thus prolonging the service life of the hollow glass.…

What Are the Routine Preparations Required When Using Activated Alumina?

What Are the Routine Preparations Required When Using Activated Alumina? Activated alumina is mainly used as an adsorbent in industrial applications such as gas drying, liquid drying, water purification, selective adsorption, and decomposition processes in the petroleum industry. Due to its strong affinity for water, activated alumina has been widely used in gas drying. The main gases that can be dried using activated alumina are acetylene, cracking gas, coke oven gas, hydrogen, oxygen, air, ethane, hydrogen chloride, propane, ammonia, ethylene, hydrogen sulfide, propylene, argon, methane, sulfur dioxide, carbon dioxide, helium, nitrogen, and chlorine. As activated alumina releases a large amount…

What is the Selectivity and Adsorption Efficiency of the Molecular Sieve Type 4A?

What is the Selectivity and Adsorption Efficiency of the Molecular Sieve Type 4A? molecular sieve type 4A is composed of silicon (aluminum) octahedra, and the central polyhedron serves as the framework structure. The intermediate space of the framework is extremely empty, forming many well-arranged pores or channels. There are metal ions in the molecular sieve, and the framework space is filled with water molecules. Cations can be exchanged, and water molecules can be removed. Under certain conditions, the framework structure can also change. The characteristics of this structure are the inherent reasons for the various properties of molecular sieves. Properties…

Regeneration Principle of Molecular Sieve in PSA Air Separation Plant

Regeneration Principle of Molecular Sieve in PSA Air Separation Plant For the PSA molecular sieve air separation plant, the molecular sieve is undoubtedly the core component of the system; only the clean compressed air is continuously adsorbed and regenerated through the molecular sieve, in order to continuously produce the nitrogen or oxygen we need. Regeneration can be understood as the reverse process of adsorption; because after the molecular sieve completes a saturated adsorption, it cannot continue to adsorb gas, and it needs to “recover” its adsorption capacity, which is what we call “regeneration”. Molecular sieve regeneration can help the molecular…

Advantages of PSA Molecular Sieve Pressure Swing Adsorption for Oxygen Production

Advantages of PSA Molecular Sieve Pressure Swing Adsorption for Oxygen Production In industry, there are three main methods for oxygen production, namely cryogenic distillation, adsorption and electrolysis, and they all use different gas separation principles; cryogenic distillation is to first liquefy air at low temperature, and then separate oxygen and nitrogen by utilizing their different boiling points. Electrolysis is the process of putting direct current into water to separate oxygen and hydrogen. The Technical Characteristics of PSA Molecular Sieve The pressure swing adsorption method was launched in the late 1950s. It uses zeolite molecular sieves as adsorbents to adsorb and…

What Conditions Need to Be Controlled for the Production of Nitrogen Using Carbon Molecular Sieves?

What Conditions Need to Be Controlled for the Production of Nitrogen Using Carbon Molecular Sieves? Carbon molecular sieve air compression purification process Purifying the raw air before entering the carbon molecular sieve adsorption tower is necessary because particles and organic atmosphere entering the adsorption tower can block the micropores of the carbon molecular sieve and gradually reduce its separation performance. There are methods to purify the raw air: 1) keeping the intake of the air compressor away from places with dust, oil mist, and organic atmosphere; 2) purifying the raw air with equipment such as a refrigerated dryer and adsorbent…
