Inert alumina ceramic ball is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the coverage of the reactor catalyst support material and tower packing, it has a high temperature high pressure, low water absorption, chemical stability characteristics, can withstand acids, alkalis and other organic solvents and can withstand the temperature of the production process changes occur. Its main role is to increase the gas or liquid distribution points, support and protect the strength of the active catalyst is not high. 
 Active ceramic ball: a novel reactor bearing filler. It is based on the inert alumina balls into a small amount of transition metal oxides. The ball with both inert and high mechanical strength, high temperature properties, from the filter, vapor-liquid dispersion, coverage, supporting a catalyst. And has certain catalytic activity in olefin hydrogenation, desulfurization and denitrification from the catalyst role. In distillate hydrotreating, hydrocracking, reforming pre-hydrogenation and hydrogenation of benzene and other manufacturing processes, in the catalyst bed reactor filled with CS-ACB activity of the top balls, secondary processing of raw oil can The olefin and diolefin the preliminary hydrogenation, thereby reducing the catalyst coke in the bottom of the catalyst bed filled with CS-ACB activity of balls can be removed some of the reaction process of mercaptan so generated. Therefore, the use of CS-ACB activity balls, not only can effectively improve the utilization of the reactor space, and to some extent, protect the catalyst is not the role of poisoning and sintering, thus prolonging the life of the catalyst. 
 High alumina ceramic grinding balls, with density, high mechanical strength, wear resistance, and is an economic model, are widely non-metallic grinding price quality. The products are widely used in machinery, electronics, aerospace and other fields. Production of user requirements but also by the tubes, rings, rods, beams, plates and parts. Balls can be used in ordinary oxygenase refinery cracking, hydrogenation physical fractionation, alkylation, catalytic reforming unit, drying tower, only liquid defluorination control light oil desulfurization and the recovery of oil, various chemicals for water treatment, fertilizer plant project reformer, active separation devices, air separation equipment, cooler, stove and to the sub-iron and steel plants, etc devices.
