Pseudoboehmite is an aluminum-based material with high specific surface area, rich pore structure and good thermal stability. Due to its unique physical and chemical properties, it plays an important role in many industrial fields. But how much do you know about its specific applications? This article will explore the main industry applications of pseudoboehmite in depth to help everyone have a more comprehensive understanding of this multifunctional material.
1. Petrochemical Industry: Catalyst Carrier
The main application of pseudo-boehmite in the field of petrochemicals is as a catalyst carrier, especially in the process of oil refining and chemical catalysis. Due to its high specific surface area and suitable pore structure, pseudo-boehmite can effectively load active metals (such as platinum, palladium, nickel, etc.), improving the dispersion and stability of the catalyst.
• Hydrogenation catalyst: In the processes of petroleum hydrorefining and hydrocracking, pseudo-boehmite as a carrier can significantly improve the catalytic efficiency and reduce the content of impurities such as sulfur and nitrogen.
• Fischer-Tropsch synthesis: In the processes of coal-to-oil and natural gas-to-oil, pseudo-boehmite-loaded cobalt-based or iron-based catalysts can improve the selectivity of hydrocarbon synthesis.
2. Environmental protection industry: adsorbent and wastewater treatment
Pseudo-boehmite has excellent adsorption properties and can be used to treat heavy metal ions (such as lead, cadmium, arsenic, etc.) and organic pollutants in industrial wastewater.
• Heavy metal adsorption: Its surface hydroxyl (-OH) can coordinate with heavy metal ions to achieve efficient removal.
• VOCs treatment: In the treatment of volatile organic compounds (VOCs), pseudo-boehmite can be used as an adsorbent or catalyst carrier to improve degradation efficiency.
3. Lithium battery industry: Lithium battery separator coating
With the rapid development of the new energy industry, pseudo-boehmite is increasingly used in lithium battery separator coatings.
• Improve thermal stability: Pseudo-boehmite coated on the surface of the separator can enhance high temperature resistance and prevent thermal runaway of the battery.
• Optimize electrolyte wettability: Its porous structure helps the uniform distribution of the electrolyte, improving the battery cycle life and safety.
4. Ceramics and refractory industry
Pseudo-boehmite can be used as a raw material for high-performance ceramics and refractory materials, and is used to prepare alumina ceramics, refractory bricks, etc.
• High-purity alumina precursor: After high-temperature calcination, pseudo-boehmite can be converted into high-purity α-alumina, which is used in high-end fields such as electronic ceramics and sapphire substrates.
• Refractory material enhancer: Adding pseudo-boehmite to refractory castables can improve the mechanical strength and thermal shock resistance of the material.
5. Pharmaceutical and cosmetic industries
Pseudo-boehmite is also used in medicine and cosmetics due to its non-toxicity, high adsorption and mild chemical properties.
• Drug sustained-release carrier: As a drug carrier, it can control the drug release rate and improve the efficacy.
• Cosmetic additive: used for oil control and absorption of excess oil on the skin, commonly found in high-end foundation and sunscreen products.
With its excellent physical and chemical properties, pseudo-boehmite plays an important role in many fields such as petrochemicals, environmental protection, new energy, ceramics, and medicine. With the advancement of science and technology and industrial upgrading, its application scope will be further expanded. In the future, by optimizing the preparation process and developing new composite materials, the market potential of pseudo-boehmite will be even greater.
