Large Pore Pseudo Boehmite

Large Pore Pseudo boehmite is non-toxic,tasteless,odorless powder (dry product).It is produced by carbonization and neutralization with aluminum hydroxide and ionic membrane alkali.This product has high purity, low stacking ratio, large pore volume, high specific surface area, and easy dispersion.

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

● Processing catalyst supports of different shapes
● Used as colorant and stabilizer in glass and enamel industry
● High quality raw materials for ink fillers

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.

Q1: How is Large Pore Pseudo boehmite different from common Pseudo boehmite?
Answer:
Common pseudo-bentonite: The pore pore volume of ≥0.3 cm³/g suitable for small molecule reactions (such as light oil hydrogenation, FCC matrix).
Large Pore Pseudo boehmite: with a pore volume of ≥0.9 cm³/g , designed specifically for the diffusion of large molecules, such as heavy oil components like residual oil and asphaltene.

Q2: Will the specific surface area of Large Pore Pseudo boehmite decrease?
Answer:
Not necessarily. Although increasing the pore diameter usually leads to a decrease in specific surface area, through the technique of loose nanoparticle packing + directional expansion (such as the neutral inorganic salt method in 2024), it is possible to maintain a pore volume of >0.9 cm³/g while achieving a specific surface area of 250–350 m²/g, balancing mass transfer and the density of active sites.
