What are the detailed differences between active and inert alumina ceramic balls? What are the differences between active and inert properties in alumina ceramic balls? From a literal understanding, it can be understood as dynamic and static. Today, I will explain the previous question:
1、The appearance of active and inert alumina ceramic balls
Active alumina ceramic balls have many capillary pores and a large surface area.
Inert alumina ceramic balls are just ordinary ceramic balls.
Characteristics of active and inert alumina ceramic balls
2、The capillary pores on active ceramic balls have an adsorption effect and can adsorb many polar substances. As mentioned before, it is dynamic, meaning that when it combines with other materials, a reaction occurs. It also has a drying and catalytic effect, and has a strong affinity for water, oxides, alkalis, and acetic acid. It has high strength, low wear, does not soften when soaked in water, does not expand, powder or crack.
Inert ceramic balls are static and do not react with other materials, providing protective functions. They can withstand high temperatures, acids, alkalis, salts, and various organic solvents' corrosion. They are mainly used as isolation materials before and after filling catalyst layers in reactions.
3、Applications of active and inert alumina ceramic balls
Active alumina ceramic balls are commonly used in petroleum cracking gas, deep drying of ethylene and propylene gas, hydrogen production, air separation units, fluoride treatment of hydrogen peroxide, and instrument drying machines. They can also remove pollutants such as sulfur dioxide, hydrogen sulfide, hydrogen fluoride, hydrocarbons, and fluorine-containing substances from waste gas, especially suitable for defluorination treatment of fluoride-containing water.
Inert ceramic balls are widely used in industries such as petroleum, fertilizers, chemicals, natural gas, and environmental protection. As support and covering materials for catalysts inside reactors, inert ceramic balls can buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas inside the reactor.
4、Names of active and inert alumina ceramic balls
Active alumina is generally not referred to as ceramic balls; only inert alumina is called ceramic balls. Active alumina is a general term, and its name will vary according to different characteristics, such as active alumina adsorbent, active alumina defluorination agent, etc.
