alumina chemical filling ball high purity filling material abrasive medium catalyst covering material
Product name : Alumina ceramic ball
Specification : HY-TCQ-01
product introduction:
Inert alumina ceramic ball ( catalyst proppant ) is the most widely used filler as catalyst carrier in the world due to its excellent stability and reliability. It is produced from high-quality chemical ceramic clay materials with good stability, high mechanical strength and thermal shock resistance, which makes their ideal choice to support all types of catalysts. It is widely used in petroleum, chemical, fertilizer, natural gas, environmental protection and other industries as a catalyst support material and tower packing in the reactor. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. Can withstand acid, alkali and other organic solvent corrosion, and can withstand the production process of temperature changes. Its main role is to increase the gas or liquid distribution point, support and protect the active catalyst strength is not high.
