Common Pseudo Boehmite

Common Pseudo Boehmite (chemical formula AlOOH·nH₂O, n = 0.08 - 0.62) is a transitional aluminum oxide with high specific surface area and large pore volume. Its wet form presents a white colloidal state, while its dry form is a white powder.Through different preparation processes, the pore volume (0.5 - 2.0 cm³/g) and specific surface area (up to 470 m²/g) can be regulated. After being calcined at 550 - 850 °C, it forms γ-Al₂O₃ or α-Al₂O₃.is powder(dry).It has high crystal phase purity, good molding performance, and thixotropic gel.

Note: The above is typical data. We can also produce per customers' request.

● It is used as the main raw material of petroleum and petrochemical catalyst carrier
● Used as molding binder for molecular sieve and silicate refractory fiber products.

Packaging: Steel drum / paper drum / aluminum foil bag or according to customer's request.
Storage: Avoid damping and any adsorption of water or organic substance before use. Otherwise it must be regenerated.

1.What are the specific surface area and pore volume of the Common Pseudo Boehmite?"
Answer: The specific surface area of the regular product is around 300 m²/g, and the pore volume is 0.3 cm³/g.
 

2.What will Pseudo Boehmite become after calcination? Is it suitable for use as a γ-Al₂O₃ carrier?"
Answer: After calcination at 550–750℃, it mainly generates γ-Al₂O₃, which has a high specific surface area (>200 m²/g) and a concentrated pore size (6–15 nm), making it highly suitable for use as a catalyst carrier in hydrogenation, methanation, etc.

3.How is the gelation performance of Common Pseudo Boehmite? Can it be used for extrusion molding?"
Answer: After gelation, the viscosity is ≤200 mPa·s, with good fluidity. It is widely used in extrusion molding, spray granulation, and is particularly suitable for the manufacture of denitration catalysts and clover-shaped carriers.
