Product Description
Product performance:
The inert alumina balls are widely used as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in many fields such as petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection etc. It has characteristics of high temperature resistance, lower water absorption, stable chemical property, and can resist corrosion of acid, alkali and other organic solvent, and can endure the temperature urgent changes occurred in production process.
