How to Select Activated Alumina for Dryers
In industrial gas and liquid processing, drying safeguards product purity, equipment safety, and process stability. Activated alumina is a high-efficiency, economical, and reliable desiccant. Its performance directly affects a drying system’s operating efficiency and total cost. So, how do yo...Read more -
Why Do Compressed Air Systems Need Dryers?
In industrial compressed air systems, the formation of moisture is an unavoidable physical phenomenon. The negative effects it brings, however, can be prevented and controlled through sound, effective measures. As a core unit in compressed-air after treatment, the correct selection and configurat...Read more -
How to Obtain Stable, High-Efficiency Nitrogen
In modern industrial production and scientific R&D, nitrogen is an essential protective and process gas, used increasingly across applications. From food packaging and electronics manufacturing to chemical production and metal treatment, nitrogen purity and supply stability directly affect pr...Read more -
Why Can’t Activated Alumina Adsorb Oil?
Activated alumina is produced by heating aluminum hydroxide to remove its crystal water. Its surface is rich in hydroxyl groups (–OH) and exposed aluminum ions (Al³⁺), which gives it high surface polarity and strong hydrophilicity. Through hydrogen bonding and electrostatic interactions, it prefe...Read more -
How Are Molecular Sieves Used for Desulfurization?
A molecular sieve is a porous material with a uniform microporous structure, composed mainly of silicon, aluminum, and oxygen. Its crystal framework contains countless cavities and channels. Because the pore size is fixed and uniform, only molecules with diameters smaller than the pore openings c...Read more -
Why Can Molecular Sieves Be Used for Ethanol Dehydration?
The application of molecular sieves in ethanol dehydration is a well-established and highly important technology in both industrial and laboratory settings. Specifically, 4A and 3A-type molecular sieves are widely used as highly efficient desiccants (adsorbents) for ethanol dehydration. They sele...Read more
