Ceramic Ball For Bed Filling

Catalyst Bed Support Media Balls are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
They have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.
The main role of catalyst bed support media is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
