The core characteristics of Zibo Xiangrun alumina ceramic balls:
· High mechanical strength
· Excellent chemical inertness (resistant to acid and alkali corrosion)
· Outstanding thermal stability (long-term operating temperature up to 1600°C+)
· Regular spherical size and uniform porosity
· Multiple sizes from 0.5-95mm
1. Petrochemical and Coal Chemical Industries
Hydrorefining/Hydrocracking Units: Used for desulfurization, denitrification, and olefin saturation. Support spheres are placed at the top and bottom of the reactor to protect the expensive hydrorefining catalyst and ensure uniform distribution of oil and gas.
Catalytic Reforming Units: Produces high-octane gasoline. Supports the bed to ensure uniform flow of the reaction stream through precious metal catalysts such as platinum-tin.
Isomerization and Alkylation Units: Supports acidic catalysts and resists acidic environments.
Functions: Bearing weight, distributing, and protecting. Prevents catalyst particles from clogging the equipment, being carried away by the gas flow, or causing excessive pressure drop in the bed.
2. Chemical Industry
Ammonia Synthesis Unit: Supports iron-based or ruthenium-based catalysts in the ammonia synthesis tower, enduring high temperature and pressure.
Hydrogen Production Unit: Protects relevant catalysts in natural gas steam reforming, shift reaction, and other processes.
Sulfuric Acid Production: Serves as a support and distribution layer in vanadium catalyst converters.
Organic Synthesis: Fixed-bed reactors in production units such as phthalic anhydride, maleic anhydride, and vinyl acetate.
3. Environmental Protection and Air Pollution Control
VOCs Catalytic Combustion Unit: Supports precious metal or metal oxide catalysts for treating organic waste gases.
Waste Gas Purification Tower: Serves as a supporting layer for the packing balls.
4. Gas Industry
Air Separation Units: Support the molecular sieve at the bottom of the molecular sieve adsorber to ensure uniform air flow, achieving deep drying and purification.
Natural Gas Drying and Purification: Support activated alumina, molecular sieves, or desulfurizing agents in drying towers and desulfurization towers.
Oxygen Generators and Nitrogen Generators: Support the adsorbent in PSA/VPSA units.
5. Other Industrial Fields
Metallurgical industry, power industry, electronics industry, pharmaceutical industry, laboratories, etc.
