Zibo Tonyear Chemical supplies chemicals which is catalyst manufacturing related, include the Pseudoboehmite, Boehmite etc which is widely used as adsorbent, desiccant, catalyst and catalytic carrier in the industrials of refinery, rubber, chemical fertilizer, petrochemical and so on. Special pseudoboehmite featured with large pore volume and huge surface area is one of the main raw materials for hydrogenation catalysts carrier.

Zibo Tonyear Chemical is a working to be an stable and high quality raw materials vendor for your catalyst, activated alumina, molecular sieve,and other specialty adsorbents manufacturing.

Pseudoboehmite

Pseudoboehmite is an aluminium compound with the chemical composition AlO(OH). It consists of finely crystalline boehmite. However, the water content is higher than in boehmite which is widely used as adsorbent, desiccant, catalyst and catalytic carrier manufacturing.

Boehmite

With excellent flow property, this product is used as catalysts support, for automobile emissions catalysts and electronic ceramic alumina which is widely used as adsorbent, desiccant, catalyst and catalytic carrier in the industries of refinery, rubber, chemical fertilizer, petrochemicals.

Application

1.Pseudoboehmite (Specialty)

Pseudoboehmite (Specialty) produced by Technique of Aluminium Sulfate is pseudo­boehmite in essential, shortly as PB. It is one of the important fine chemicals, typical of abundant micro volume structure, huge surface area and proper surface alkalinity or acidity. Thus, it is widely used as adsorbent, desiccant, catalyst and catalytic carrier in the industries of refinery, rubber, chemical fertilizer, petrochemical and so on. Special pseudoboehmite featured with large pore volume and huge surface area is one of the main raw materials for hydrogenation catalysts carrier.
