The surface of alumina packing ball is rough, and no matter the diameter size, it is rolled into ball. Alumina packing ball is used as the cover supporting material and tower packing of the catalyst in the reactor, and can withstand the temperature changes in the production process, its main role is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength. About technical indicators, alumina packing ball is mainly used as proppant, so it will pay attention to compressive strength, water absorption, tolerance size, temperature resistance to sharp changes, etc.
