The Quality of Activated Alumina Itself: Activated alumina used in air separation units needs to maintain good particle integrity during long-term airflow flushing and periodic regeneration. If the mechanical strength of the particles is low, they are prone to breakage during loading and operation, forming more and more fine powder. These dust particles not only […]

Many customers ask a question when selecting activated alumina: Is smaller particle size of activated alumina for air separation equipment better? Under certain conditions, smaller activated alumina particles can indeed shorten the mass transfer distance for moisture entering the particles and help improve the mass transfer rate. However, for air separation equipment and fixed-bed adsorption […]

Why Does Activated Alumina Produce Dust? Activated alumina is usually loaded into the adsorption bed in the form of spherical particles. During transportation, loading and unloading, and equipment operation, collisions and friction may occur between the particles. If the mechanical strength of the activated alumina is insufficient, or if the particles themselves contain a large […]
