Alumina Balls
Alumina balls feature a high strength, high chemical durability and great thermal stability. They can resist high temperatures, high pressures, and the corrosion caused by acids, bases, salts, and all kinds of organic solvents, making them ideal for use in petroleum, chemical, fertilizer, natural gas, environmental protection and other industries. As the catalyst covering-blocking material and filling material in reactors, alumina balls are primarily used to increase the distribution sites of gas and liquid, as well as support and protect the activated catalyst when said catalyst is not very strong. They are widely used as rebasing-filling material for hydrocracking devices, refining devices, catalytic reforming devices, isomerizing devices, and demethylation devices in petrochemical plants, chemical fiber factories, alkyl benzene factories, aromatic hydrocarbon factories, ethylene plants, natural gas factories and more.
