 For Catalysts

Pseudo boehmitis an aluminum compound with the chemical composition AlO(OH).

It consists of finely crystalline boehmite. However, the water content is higher than in boehmite.

 

Pseudoboehmite is used as binder for FCC catalysts and adsorbents,
also a raw material for activated alumina and abrasives.

 

Pseudo-boehmite is white powder with high purity, odorless, tasteless,,low pile, large pore volume,
high specific surface,good compatibility, excellent gelation and strong caking property.
It can be easily decentralized and soluble in the acid and alkali solution.
It can become highly active alumina after low-temperature roasting and dehydration.

 

It is a binder of cracking catalyst for semi-synthetic rare-earth Y molecular sieve,
a binder in aluminum silicate refractory fiber, a catalyst in making ethylene by alcohol dehydration and in making epoxy ethane.

It also can be used as raw material for activated alumina and other aluminates and abrasives.
