99% High Alumina Ceramic Ball (وسائل الإعلام المحفز وسائل الإعلام) is made from alumina powder with low silicon content. Its high purity and high strength give excellent resistance to high temperature, and using this inert media prevents silica from leaching out of the support inside the reaction tower, which protects downstream equipment from fouling and keeps the catalyst from being dirtied or poisoned. This makes the balls a suitable support medium for all types of catalyst. They are used widely in the petroleum, chemical, fertilizer, غاز, and environmental-protection industries, where they serve in reactors as support and cover material above and below the catalyst bed and as tower packing. The balls resist high temperature and high pressure, have a low water-absorption rate, and remain chemically stable; they withstand attack by acids, alkalis, and organic solvents and endure the temperature changes that occur during operation. Their principal function is to increase the number of gas- and liquid-distribution points and to support and protect the lower-intensity, lower-activity catalyst.
