92% High Alumina Ceramic Ball
Products Description
High Alumina Ceramic Ball, also known as inert alumina ceramic ball, is a support material for reaction towers used in petroleum, chemical, fertilizer, natural gas and other industries. It is used as a covering and support material for catalysts or adsorbents in reactors, and as filler The main function of porcelain balls is to increase gas or liquid distribution points, support and protect catalysts and adsorbents with low strength, and extend operating life.
Inert ceramic balls are widely used in the oil refining industry, petrochemical industry, and natural gas refining industry as catalysts or support materials for absorption layers. They have incomparable characteristics of impact resistance, temperature resistance and crushing strength.
Due to its excellent chemical resistance, it is suitable for olefin process applications where polymerization problems exist, such as ethylene dryers
Super Packing Mall 92% High alumina Ceramic Ball, has superior chemical resistance and very excellent thermal properties, with its high density high-temperature resistance 1550℃, also it's a good choice for heat retention or equilibration media.
Application
a) It's a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
b) It's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.
