Middle Alumina Ceramic Ball for packing and grinding

Middle Alumina Ceramic Ball for packing and grinding

Short Description:

Mid -Alumina ceramic 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 inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.

Middle Alumina Ball Features

1) Spheres (balls) or cylinders
2) Very excellent support and covering media
3) Function as support media for catalyst beds or other chemical beds in reactors or towers
4) Very excellent performances and stability in acid and other chemical surroundings
5) Very good chemical stability and low rate of water absorption
6) Can withstand high pressure and high temperatures
7) Can be even used in hot caustic service because they can resist over 10% sodium hydroxide service up to 60ºC, and 1% sodium hydroxide service temperature up to 100ºC
8) Can also resist the chemical corrosions of any acid (including organic and inorganic acids, but except HF acid), most of alkali and organic solvent
9) Will increase the distributors of liquid and gas, supporting and protecting the catalyst and avoid poisoned
