Pseudo-boehmite Series product
Product property
It is known as aluminum hydroxide dry glue,the hydrate aluminum,false boehmite,with characters of non-toxic,tasteless,odourless,white colloidal(wet) or powder(dry),high purity, crystal phase forming performance is good,has the characteristics of the thixotropic gel.According to the production process of different products for applications,companies with high purity aluminum hydroxide and alkali ionic membrane on the basis of raw material,after the carbonate with different process,produce a series of plans to thin diaspore products,the series of products,the series of products with stable quality and excellent physical properties,favored by domestic research institutions and catalyst.
Used mainly
Used in petroleum chemical industry,oil refining, rubber, chemical fertilizer, nitrogen fertilizer, pharmaceuticals, refractories, environmental protection and other industries of the adsorbent, desiccant, adhesive, catalyst or catalyst carrier.
It Has been widely used in petroleum distillate hydrogenation catalyst, cracking(gasoline hydrofining catalyst,ceramic grinding tool and refractory fiber and other fields.

Pseudoboehmite,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 also known as aluminum hydroxide gelatin, alumina monohydrate, false water boehmite.It's molecular formula AI2O3.H2O,produced by sodium aluminate solution and carbon dioxide gas as raw material, with a special glue technology process.
This series of aluminum hydroxide glue products with its stable high quality and excellent physical and chemical properties, has been widely used in various petroleum distillate hydrogenation catalyst, coal tar hydrogenation catalyst,pyrolysis gasoline hydrogenation fine catalyst, a variety of chemical catalyst production.
Because of its lack of chloride and sulfur ions,this kind of aluminum hydroxide, using in project is first choice,especially the various types of organic synthesis catalyst research and production .
