Features:
1.Catalyst Bed Support Media
2.Composed of sintered α-alumina with very low impurity levels for High Alumina products
3.Acid and Alkali Resistant, essentially inert in most chemical environments
4.The low silica content of High Alumina balls are an excellent choice for high temperature applications in the presence of reducing atmospheres, where silica leaching must be held minimal, such as in reformers for synthesis gas production.
5.The low level of other impurities make High Alumina balls an excellent recommendation for supporting adsorbents used to purify reactive monomers such as ethylene and propylene.
