Inert alumina ceramic balls widely used in petroleum, chemicals, fertilizers, natural gas and environmental protection industries, as a coverage supporting material of catalyst in the reaction and tower packing, it can bear high temperature and high pressure and low water absorption and its chemical characteristics is stable. It’s able to resist the corrosion of acid, alkali and other organic solvents, and can bear the temperature change in the product process. It can mainly increase the distribution of gas or liquid, support and protect activity catalyst of low intensity.
Chemical composition:
