Product Description

Inert Alumina Ceramic Balls with Low Wear Rate for Industrial Towers

Inert ceramic ball support Media are the most widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.

Core Properties and Advantages (Key for Chemical and Petroleum Applications)

 

• 1.Chemical Stability: Resistant to strong acids (HCl, H2SO4), strong alkalis, H2S, SO2, organic solvents, and high-temperature oil/gas corrosion except for hydrofluoric acid. It does not react with process media or contaminate products.
• 2.High Temperature and Thermal Shock Resistance: Can withstand long-term exposure to temperatures above 1000°C without cracking under rapid cooling and heating, making it suitable for high-temperature processes such as hydrogenation, reforming, and cracking.
• 3.High Mechanical Strength and Low Wear: With a Mohs hardness of 9 and high compressive strength, it features extremely low wear rates during loading and long-term operation, ensuring stable pressure drop in the bed.
• 4.Inertness and Insulation: Non-conductive and non-catalytic, it prevents galvanic corrosion and protects catalysts and tower equipment.
• 5.Fluid Distribution: Regular spherical shape and graded loading enable uniform distribution of gas and liquid, reduce channeling, and enhance mass transfer and reaction efficiency.

 

Typical Application Scenarios and Functions

 

• 1.Refining Units (Catalytic Cracking, Hydrofining, Reforming, Isomerization): Used as bottom supports for reactors/towers and top coverings for catalysts; they buffer feed impact, prevent catalyst pulverization and loss, and ensure uniform gas and liquid distribution.
• 2.Coal Chemical/Natural Gas Chemical Industry (Synthetic Ammonia, Methanol, Methanation, Secondary Reformer): Support sulfur-tolerant shift and methanation catalysts under high temperature and high pressure, and resist corrosion from reducing atmospheres such as H2 and CO.
• 3.Absorption/Desorption/Distillation Towers (Desulfurization, Decarbonization, Aromatic Extraction, Solvent Recovery): Serve as fillers or support layers to reduce pressure drop and strengthen gas-liquid contact.
• 4.Environmental Protection Equipment (Flue Gas Desulfurization, VOCs Treatment): Enhance spray absorption efficiency and improve purification performance.

 

Standard Specifications, Grading and Applicable Standards

Common diameters: Φ6, Φ10, Φ13, Φ16, Φ20, Φ25, Φ38, Φ50 mm.

• Grading principle: Layered loading with large → medium → small balls from the tower bottom to the catalyst bed (e.g., Φ50→Φ25→Φ13→Φ6) to prevent catalyst leakage and optimize fluid distribution.
