The other day, a Korean customer sent a rigorous inquiry regarding their high-pressure hydrotreating project, focusing on the strength and stability of their ceramic balls. Based on their demanding operating conditions of 8.0 MPa and 380°C, we precisely recommended 95% alumina ceramic balls. So, why did they choose 95% alumina ceramic balls?
Excellent Crush Strength: Our recommended 95% alumina ceramic balls boast a crush strength consistently exceeding 150N/particle, providing ample safety margins to effectively prevent pressure-induced pulverization and ensure long-term stable bed pressure drop.
Excellent Thermal Stability and Chemical Inertness: The 95% alumina content ensures extremely high chemical inertness. Furthermore, our specialized sintering process allows them to withstand high temperatures up to 1600°C and operate comfortably at 380°C, effectively eliminating any instability in the reactor.
Extreme Hardness and Wear Resistance: 95% alumina ceramic balls have a Mohs hardness of 9 and a wear rate of less than 0.08/%, ensuring they maintain integrity and a long life even under high-velocity fluids.
Where else can 95% alumina ceramic balls be used?
They are widely used as padding materials in hydrocracking units, refining units, catalytic reforming units, isomerization units, and demethylation units in petrochemical plants, chemical fiber plants, alkylbenzene plants, hydrocarbon plants, and ethylene plants. They also serve as support and coating materials for catalysts, molecular sieves, desiccants, and other components within reactors, as well as tower packing. Their primary function is to increase gas or liquid distribution points and to support and protect weakly active catalysts.
Petrochemical Industry:
Catalytic Reforming Units: Serves as a catalyst support and cover ball to protect expensive platinum-based catalysts.
Isomerization and Dehydrogenation Reactors: Provides a stable catalyst bed under similarly harsh conditions.
Ethylene Cracking Gas Drying Towers: Serves as a support material to ensure stable operation of gas purification units.
Gas Purification and Environmental Protection:
Natural Gas Desulfurization and Dehydration Towers: Serves as a support material for desulfurizers and dehydrators to ensure the purity of domestic and industrial gas.
Volatile Organic Compound Treatment Units: Serves as a catalyst carrier (or protective agent) in catalytic combustion reactors, helping to meet environmental standards.
