Inert aluminum oxide ceramic balls are widely used in many fields, including petroleum, chemical engineering, fertilizer production, and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
They have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.
The main role of inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
Inert alumina ceramic balls are widely used in petroleum, chemical, fertilizer, and environmental protection industries, as a support material for the catalyst in the reactor and tower packing. Inert alumina ceramic ball has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, bases and other organic solvents and can withstand the temperature changes that occur during production. The main function of the inert alumina ceramic ball is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.
 
Alumina supported catalyst for hydrogen production has the following characteristics:
1. High hydrogenation activity: Nickel has outstanding activity for promoting hydrogenation reactions.
2. Excellent mechanical and chemical stability: The alumina support provides high mechanica strength and thermal/chemical stability.
3. High selectivity: lt exhibits high hydrogenation activity and high selectivity under suitable conditions.
4. Regenerability: The oxidized catalyst can be regenerated by reduction treatment.
5. Wide pH range: It operates stably in a wide pH range from 0 to 14.
6. Low cost: Nickel and alumina are relatively inexpensive raw materials, allowing for an economical catalyst.
 
Using alumina as the support and nickel as the primary active component, this catalyst is widely used for hydrogenation dearomatization of aviation kerosene, hydrogenation of benzene to cyclohexane, hydrogenation of phenol to cyclohexanol hydrotreating, hydrofining of industrial hexane, and hydrogenation of unsaturated aliphatic andaromatic hydrocarbons such as white oil and lubricating oil lt can also be used for efficient Liquid-phase desulfurization and as a sulfur protective agent in catalytic reforming processes. This catalyst has high strength and excellent activity. n hydrogenation refining processes, it can reduce aromatic or unsaturated hydrocarbons to the ppm level. The catalyst is in a reduced state for stabilization.
