Activated alumina is usually filled in the adsorption bed in spherical or approximately spherical particles. When compressed air or feed air passes through the adsorbent bed, the moisture in the air comes into contact with the activated alumina particles and is adsorbed by the pores. Particle size will directly affect the flow state of the […]
Why Is Potassium Permanganate Activated Alumina Affected by Humidity? When the moisture in the gas increases, water molecules also interact with the surface and pores of activated alumina. If the humidity is at a relatively high level, water may occupy part of the surface and pore space, causing changes in the ability of target pollutants […]
Spherical particles have a relatively regular shape and, with relatively uniform particle sizes, are more likely to form a stable adsorbent bed. For potassium permanganate activated alumina, this is particularly important because its actual performance depends not only on the chemical properties of the material itself, but is also closely related to the residence time […]
