activated alumina packing, a critical tower internal in industrial processes, often generates heat during operation due to inherent characteristics. One primary reason is the exothermic nature of its adsorption process. When activated alumina comes into contact with moisture or specific gases, it undergoes hydration reactions, releasing heat. For instance, the reaction of Al₂O₃·nH₂O with water vapor to form Al₂O₃·(n+1)H₂O releases adsorption enthalpy, leading to localized temperature rises. This is particularly noticeable in gas drying or purification systems where moisture removal is the core objective.

Another key factor contributing to heat generation is mass transfer resistance within the packing. In packed towers, gas and liquid phases flow through the pores and channels of activated alumina packing, creating resistance to mass transfer. As components in the fluid move across the packing surface, energy is consumed, and some of this energy converts into heat due to frictional forces and the inefficiency of mass transfer processes. Over time, this accumulated heat can affect the overall performance of the tower, reducing efficiency and potentially causing operational issues.
Additionally, the presence of catalytic impurities or reactions can amplify heat generation. Activated alumina, while primarily used for adsorption, can act as a catalyst support in certain applications. If the feedstock contains reactive substances, the catalytic activity of the packing may trigger unwanted chemical reactions, such as oxidation or decomposition, which are highly exothermic. For example, in refinery distillation towers, activated alumina packing might catalyze the breakdown of hydrocarbons, releasing significant heat that must be managed to prevent overheating.
