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.
Inert ceramic balls are generally used as the support and covering material of the catalyst in the reactor, which can buffer the impact of the liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquids and gases in the reactor. It has the characteristics of high temperature and high pressure resistance, low water absorption, stable chemical properties, and can withstand the corrosion of acids, bases and other organic solvents, as well as temperature changes in the production process. Due to the wide range of uses, the economic benefits brought by inert porcelain balls are considerable.
