Ceramic Alumina Balls
The ceramic alumina balls which are high purity inert product which act as a true bed support for an adsorbents & active catalysts, These ceramic alumina ball has stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties. These are capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid , and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.
Sorbead India is a ceramic balls manufacturers in India
Sorbead India offers these inert ceramic balls for typical applications, widely used as covering and supporting catalysts in reaction vessels and as packing in towers. The primary role of these ceramic balls is to increase the distribution spots of gas or liquid and support and protect the activating catalyst with low strength. Ceramic Alumina balls are available in round shapes, in sizes of 3, 6, 13, 19, 25, 37 & 50 mm.
Applications Inert Catalyst Bed Support Balls
- These are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection
- Ceramic alumina balls used as catalyst support as refractory ball supports in hydrocarbon industries, refractory bed support of high purity type
- They are used as inert catalyst supports in secondary reformers of ammonia manufacturing plants and as inert supports in oil refineries and chemical process plants
