Application: Its main function is to increase gas or liquid distribution points, catalyst support and protection intensity is not high life. Properties: A - 99 ALMELT ® catalyst support ball is by the very low silicon content of calcined ά alumina powder, high purity and high strength make it easy to high temperature resistant, as A catalyst in the reactor to cover made of material, it is resistant to high temperature and high pressure, bibulous rate is low and stable chemical properties, can withstand the erosion of acid, alkali and other organic solvents, and able to withstand in the production process of temperature change.
