PURAL / CATAPAL
PURAL and CATAPAL are the respective tradenames for the high-purity alumina hydrates manufactured in Brunsbüttel, Germany, and Lake Charles, Louisiana, USA. PURAL and CATAPAL are white, free-flowing powders whose unique combination of purity and controllable physical properties make them excellent starting materials for many products. This family of alumina hydrates (boehmite, AlOOH, and bayerite, Al(OH)3) has historically been chosen as supports or binders for catalysts in refinery and chemical processes. Recent developments in many other applications have demonstrated these unique aluminas have applications in areas far beyond catalysts.
