Description
1. Product Description
The low silica content makes 99% alumina ballsan excellent choice for high temperature applications in the presence of high water partial pressures, where silica leaching must be held minimal, such as in reformers for synthesis gas production.
It has high strength, high stabilities to chemical and thermal circumstances. It can resistant to acid alkali, salt and all organic solvents. Being used as a support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environment protection industries, it can improve the distribution of gas and liquid; protect the catalyst from shocking by the rushing fluids.
