High-alumina Support Medias Ceramic Ball (99% Al2O3)
1. Product Description
High Oxide Inert Alumina Balls for Heat Retention Catalyst Support
are widely used in many fields, including petroleum, chemical engineering, fertilizer production, 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.
We Pingxiang chemshun ceramics Co., Ltd a professional enterprise with more than 18 years manufacturer and export for the catalyst support matieral, chemical packings. we can provide the most cost-efficiency products to you.
2. The advantages of the High Oxide Inert Alumina Balls for Heat Retention Catalyst Support
-- High purity. the alumina content is high to 99%. The high purity, low silica and high strenthg make this balls an ideal seletion for the high-temperature and steam applications, where the environment should be avoid the problem of leached silica coating downstream equipment or fouling or polluting the catalyst bed.
-- Excellent thermal and mechanical shock resistance proerties. With the excellent of thermal and mechanical shock resistance properties and the high density, Chemshun alumina ceramic ball 99% are able to work on temperature up to 1500ºC.
-- Excellent chemical stability with strong resisting of acid, alkaline and organic impregnant make it suitable for applications in olefin processes such as ethylene dryers, where polymerization could be a problem.
3. The application of High Oxide Inert Alumina Balls for Heat Retention Catalyst Support
-- Desulfurizers
-- Dehydrogenation
-- Catalytic reforming
-- Catalytic isomerization
-- Ethylene cracking and drying
-- Polymerization
-- Low temperature shift
-- High temperature shift
-- Methanator
