Inert ceramic ball has high strength, high chemical and thermal stability characteristics, it can be high temperature, high pressure and acid, alkali, salt and various organic solvents, corrosion, and are widely used in petroleum, chemical, natural gas and environmental protection industries. Examples of the catalyst support and the covering material in the reactor, can be buffered into the discharge of liquid in the reactor and the impact of the gas on the catalyst to protect the catalyst, and to improve the distribution of the liquid and the gas in the reactor.
