The production method of pseudo-boehmite

Natural or artificially produced alumina monohydrate and trihydrate alumina cannot be used 

as desiccants, adsorbents, catalysts and catalyst carriers due to their low specific surface area, small pore volume and low activity.

Alumina monohydrate or trihydrate must be processed into pseudoboehmite. 

Pseudo-boehmite has high specific surface area, large pore volume, large pore size and high activity, 

It is suitable for use as desiccant, adsorbent, catalyst and catalyst carrier in the fields of petrochemical industry, fertilizer and exhaust gas.

1.Pseudo-boehmite prepared by carbonization pseudo-boehmite is prepared by carbonization

2.Production of pseudo-boehmite by alkali method

3.Pseudo-boehmite is produced by acid method

4.Pseudo-boehmite is produced by double aluminum method

5.Alkoxide method.
