Large pore pseudoboehmite/macroporous pseudo boeohmite/aluminum hydroxide dry glue

The pore volume of our macro porous pseudoboehmite is 0.8-1.2ml/g. It adopts tray dry. It is highly welcomed in the world.

Macro pore volume pseudoboehmite

is also called aluminum hydroxide dry glue or macroporous pseudoboehmite, a hydrate alumina, false monohydrate soft diaspore. It can used in different application according to the different production process .We use high purity aluminium hydroxide and ionic membrane alkali as raw materials, after the carbonation to produce series of macroporous pseudo boehmite( macroporous pseduboehmite) with different process.

Classfication of Macroporous Pseudoboehmite:

  • Normal Psudoboehmite
  • Low sodium(soda) Pseudoboehmite
  • Large pore(Macroporosity) Pseudoboehmite

Characteristics of Macroporous Pseudoboehmite:

  • Highpeptizing ability
  • Large surface area and big pore volume

 Application of macroporous pseudoboehmite:

Macroporous Pseudoboehmite is widely used in petroleum distillate fuel hydrogenation catalyst, and pyrolysis gasoline hydrogenation catalyst and chemical catalyst, and other fields.

Storage of macroporous pseudoboehmite:

  • Avoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied..
  • It should be stored in dry and ventilated warehouse to prevent contamination or moisture.
