Pseudo Boehmite
CAS NO. 1344-28-1
MF:ALOOH.NH2O
Product Performance:
A white gel (wet) or powder (dried), odorless, tasteless and nontoxic. It is a thixotrope with the characters of high purity crystalline phase, EXCELLENT GELATION and strong caking property.
It is a cement of the cracking catalyst for semi-synthetic rare-earth Y molecular sieve, a cement 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.
Usage
pseudoboehmite are widely used as adsorbent, desiccant, catalyst or catalyst carrier in oil refining, rubber, fertilizer and petrochemical industry.
pseudoboehmite has been widely used in petroleum distillate hydrogenation catalyst, cracking catalyst(gasoline hydrofining),chemical catalyst and other area.
