Pseudo Boehmite | High-Purity Alumina Precursor for Catalysts & Adsorbents

1. Product Introduction & Core Advantages

Aogochem's Pseudo Boehmite is a highly versatile, nanocrystalline form of aluminium oxide hydroxide (γ-AlOOH), serving as the premier precursor for high-performance alumina materials. Its defining characteristics are an extremely high surface area (200-400 m²/g) and a unique, gelatinous or dispersible morphology. This reactive structure allows it to be easily formed, extruded, or coated, and upon controlled calcination, it transforms into high-purity, high-surface-area gamma-alumina (γ-Al₂O₃), the workhorse support in catalysis.

Pseudo Boehmite is a critical raw material in catalyst manufacturing, primarily functioning as both an active binder and the primary source of the catalyst carrier. It is indispensable for producing shaped catalysts (e.g., extrudates, spheres) used in hydroprocessing (hydrotreating, hydrocracking), catalytic reforming, and automotive emission control. For catalyst manufacturers and chemical plants in MENA and CIS, it ensures the production of robust, high-activity catalysts essential for fuel refining and chemical synthesis.

We supply Pseudo Boehmite with tailored properties such as specific pore volume, peptizability, and impurity levels (low Na, Fe, Si) to meet precise formulation needs. Its consistent quality guarantees reproducible catalyst performance. Partnering with Aogochem provides access to this foundational material, deep expertise in catalyst manufacturing processes, and a reliable supply chain tailored to the growing catalyst production sector in strategic markets.

2. Technical Specifications & Performance Data

The performance of Pseudo Boehmite as a precursor is determined by its physicochemical properties, which Aogochem carefully controls.

3. Primary Application Industries

Pseudo Boehmite is the cornerstone material for manufacturing a wide array of industrial catalysts and adsorbents.

• Catalyst Manufacturing (Primary Application):

• Binder & Matrix Component: Provides green strength during shaping (extrusion, pelleting) and transforms into a strong, porous alumina matrix upon calcination, holding active components (zeolites, metals) together.

• Catalyst Support Precursor: The primary source material for generating the high-surface-area gamma-alumina support in catalysts for hydrotreating, hydrocracking, reforming, and syngas processes.

• Adsorbent Production: Used to manufacture activated alumina desiccants, fluoride removal media, and specialized adsorbents by forming and calcining shaped bodies.

• Ceramics & Coatings: As a reactive alumina source in fine ceramics, composite materials, and as a coating agent for catalytic substrates like honeycombs.

• Petroleum Refining & Petrochemicals: Indirectly supports the entire industry by being the essential material to produce the catalysts that enable modern refining and chemical processes.

4. Why Partner with Aogochem for Pseudo Boehmite?

Aogochem is a strategic supplier of this critical catalyst raw material, focusing on quality and consistency for your manufacturing success.

• Tailored for Catalyst Formulators: We don't offer a one-size-fits-all product. Our Pseudo Boehmite can be customized in terms of peptizability, pore structure, and chemistry to match your specific shaping process (extrusion, spray-drying, oil-drop) and final catalyst performance requirements.

• Focus on Purity & Consistency: Low and consistent impurity levels (Sodium, Iron) are non-negotiable for catalyst performance and lifetime. Our stringent quality control ensures every batch meets specifications, giving you reproducible results in your catalyst production.

• Understanding of the Catalyst Value Chain: We understand that Pseudo Boehmite is not the final product but a key determinant of your catalyst's quality. We provide technical support rooted in an understanding of the entire catalyst manufacturing and application process.

• Reliable Partner for Industrial Growth: As catalyst production expands in MENA and CIS to support local refining and petrochemical growth, Aogochem is committed to being a dependable, high-quality supplier of this foundational material.

5. Handling & Operational Guidelines

• Storage: Store in a cool, dry, and sealed environment in original packaging. Pseudo Boehmite is hygroscopic and can absorb moisture from air, which may alter its handling and peptization properties over time.

• Processing (Slurry/Peptization): For use as a binder, it is typically peptized (dispersed) in an acidic medium (e.g., nitric acid, acetic acid) to form a stable, viscous gel or slurry. The acid type, concentration, and mixing procedure are critical and must be optimized for each formulation.

• Shaping & Drying: The peptized mixture is combined with other catalyst ingredients (active phases, fillers) and shaped via extrusion, spray-drying, etc. Gentle drying is required to prevent crack formation.

• Calcination: The final, crucial step. Shaped bodies are calcined at carefully programmed temperatures (typically 400-600°C) to convert the Pseudo Boehmite binder into strong, porous gamma-alumina, developing the final catalyst's mechanical strength and porosity.

• Safety: While generally low hazard, use standard PPE (dust mask, gloves, safety glasses) when handling fine powder to avoid inhalation or eye irritation. During peptization with acid, follow appropriate chemical handling procedures. Refer to the Safety Data Sheet (SDS).
