The 99% high alumina ceramic ball (catalyst carrier medium) is made of alumina powder with low silicon content. High purity and high strength make it have extremely high temperature resistance, which is used to prevent silica from covering the leaching reaction tower of downstream equipment or fouling or poisoning the catalyst carrier. This makes them ideal for various catalyst supports.
Application:
99% high alumina ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as catalyst covering carrier materials and tower packing in reactors. It has high temperature and pressure resistance, low water absorption, stable chemical properties, resistance to acid, alkali and other organic solvents, and can withstand the effects of temperature changes during the production process. Its main function is to increase the distribution point of gas or liquid, support and protect the catalyst with low activity.
