Catalyst Bed Support Inert Alumina Ceramic Ball 3-50mm 99% Inert Alumina Ball
Catalyst Bed Support Inert Ceramic Alumina Packing Ball,High quality alumina ceramic ball, 3-50mm 99% Inert Alumina Ball
Inert Ceramic Alumina Packing Ball Detail
Introduction:
Inert Ceramic Ball has stable chemical features and a low rate of water absorption, resistant to high temperature and high pressure. It is also resistant to the corrosion of acid, alkali and some other organic solvents. They can stand the rapid changes in temperature during the manufacturing process.
Application:
Inert Alumina Ceramic Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection, etc. Which function mainly as the covering and supporting materials for catalyst in reactors and packing for towers. Its principal role is to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which has the relevantly lower mechanical strength.
Chemical Characteristics for Inert Alumina Ceramic Ball
In accordance with the different content of AL2O3, it can be divided into as follows:
