The catalyst alumina ball is made of alumina ultrafine powder, advanced molding technology and high-temperature tunnel kiln sintering. The catalyst alumina ball has the characteristics of high strength, high chemical stability, low water absorption and thermal stability. It can withstand high temperature, high pressure, acid, alkali, salt and other corrosion, and can withstand the temperature changes in the production process. The catalyst alumina ball is the key component in the catalytic process of refinery,gas processing and petrochemical industry. As the support and cover material of catalyst in the reactor, its can buffer the impact of liquid and gas entering the reactor on catalyst, support and protect the active catalyst with low strength, and improve the distribution of liquid and gas in the reactor. Its main function is to act as packing material and at the same time to support the catalyst bed in order to prevent breakthrough or loss of catalyst or adsorbent materials downstream of the reactor vessels due to the high pressure and temperature during the operation.
