Alumina ceramic balls and inert alumina ceramic balls (catalyst proppants) are the most widely used catalyst support fillers in the world because of their excellent stability and reliability. Produced from high quality Chemi clay material, they have good stability, high mechanical strength and thermal shock resistance, which makes them ideal for supporting all types of catalysts.
According to the content of alumina, it is divided into 20-30% AL2O3 ordinary ceramic balls, 31-45% AL2O3 ceramic balls, 46-70% AL2O3 ceramic balls, 71-90% AL2O3 ceramic balls, 92% alumina support balls and 99% alumina support balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as covering support materials for catalysts in reactors and tower packing. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature changes in the production process. Its main function is to increase gas or liquid distribution points, support and protect active catalysts with low strength.
