Uses: Widely used in petrochemical plants, chemical fiber plants, alkylbenzene plants, aromatics plants, ethylene plants and other plants hydrocracking equipment, refining equipment, catalytic reforming equipment, isomerization equipment, demethylation equipment, etc. . As a support covering material and a column packing of a catalyst, a molecular sieve, a desiccant or the like in the reactor. Its main role is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.

Features: high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability and stable chemical properties.

According to the content of inert alumina ceramic ball AL2O3, filler ceramic balls are divided into: ordinary porcelain ball, inert alumina ceramic ball, medium aluminum porcelain ball, high aluminum porcelain ball, 99 high aluminum porcelain ball, convex and concave groove open hole porcelain Ball, active porcelain ball, open-hole porcelain ball, micro-porous porcelain ball, regenerative porcelain ball.

 Inert porcelain balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as a supporting material for the catalyst in the reactor and tower packing. The inert ceramic ball has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, bases and other organic solvents and can withstand the temperature changes that occur during production. The main function of the inert ceramic ball is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.

★ The convex and concave grooved open ceramic ball is a new product developed on the basis of the open hole porcelain ball. The convex and concave grooved open ceramic ball is opened with the diameter of the sphere as the axis, and the groove is formed on the surface of the sphere and the convex and concave body is presented. It not only increases the specific surface area and void ratio of the sphere, but also reduces the stacking weight of the product. Thereby further increasing the dispersibility and flux of the material and reducing the resistance of the system. As a catalyst, the new type of high-efficiency support covering filler can be widely used in petroleum, chemical and natural gas industries.

★ The active ceramic ball is made by adding a small amount of transition metal oxide to the inert ceramic ball. The active ceramic ball not only has the characteristics of high temperature resistance, high pressure and high mechanical strength of the inert ceramic ball, but also functions as filtration, dispersing vapor-liquid cover, supporting the catalyst, and has certain catalytic activity, which is in the olefin saturation and denitrification. Promoting.

★ The open-hole porcelain ball is opened on the inert alumina ceramic ball to increase its specific surface area and void ratio, and has the characteristics of small pressure drop and large flux.

★ Microporous ceramic balls are made of pores on the basis of inert alumina ceramic balls to increase the porosity by 20~30%.
