professional factory for Hollow Floating Ball Factory - 92% Inert Alumina Ball – Catalyst Support Media – Kelley Detail:
Application
92% AL2O3 inert alumina ball is widely used in petroleum, chemical, fertilizer, gas, environmental protection and other industries. It is used as a catalyst covering carrier material and tower packing in the reactor. It has high temperature resistance, high pressure, low water absorption, stable chemical performance, and Withstand the erosion of organic solvents such as acids and alkalis, and can withstand temperature changes during the production process. Its main function is to increase the distribution point of gas or liquid, support and protect the catalyst with low strength.
