- Product Description
-
Alumina ceramic balls (catalyst support agents) are widely used in industries such as petroleum, chemical, fertilizer, natural gas, and environmental protection as covering support materials for catalysts in reactors and tower fillers. It has the characteristics of high temperature and high pressure resistance, low water absorption rate, and stable chemical properties. Can withstand corrosion from acids, alkalis, and other organic solvents, and can withstand temperature changes that occur during the production process. Its main function is to increase the distribution points of gas or liquid, support and protect active catalysts with low strength.
