Features of Inert Ceramic Balls Inert ceramic balls have stable chemical features and a low rate of water absorption, inert ceramic balls can resist high temperatures and high pressure. Inert ceramic balls can also resist the corrosion of acid, alkali and some other organic solvents, inert ceramic balls are able to stand the thermal shock (sharp change of temperature) during the chemical reaction process. The main role of these inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the catalyst of low strength in the reactors (a column or a tower). Inert Ceramic Balls have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process. Applications of Inert Ceramic Balls As refractory bed top plugs and supports in order to protect the catalyst bed from thermal impurities so that the catalyst bed is kept intact in spite of wide pressure variation. Inert Ceramic Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection, etc. Catalyst Bed Support media are used routinely in the following specific services: Ammonia plants, Hydrotreaters, Bender treaters, Isomerization units, pretreaters and reactors, Molecular sieve units, Diesel hydrotreaters, Naphtha treaters, Fixed bed reformers, Reformer pretreaters, Fluidized pollution control, Hydrocrackers (1st stage), Hydrogen plants. Inert Ceramic Balls are widely used in many fields, including: petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers. Packing By plastic bag, each bag 25kgs net, palletized. By super sacks, each big sacks 1000-1400kgs net, palletized. By steel drum, each drum 300kgs net, palletized.

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.
