Inert Alumina Ceramic Packing Ball
Product Detail
Inert alumina packing balls are widely used in petroleum, chemical industry, chemical fertilizer, natural gas, environmental protection and other industries, as the covering support materials and tower packing of catalyst in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature change in the production process. Its main function is to increase gas or liquid distribution point, support and protect the active catalyst with low strength.
