High-purity alumina hydrates
PURAL and CATAPAL are the respective trademarks for the high-purity alumina hydrates manufactured in Brunsbüttel, Germany, and Lake Charles, Louisiana, USA. PURAL and CATAPAL are available as 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, AIOOH, and bayerite, AL(OH)³) has historically been chosen as supports or binders for catalysts in refinery and chemicals processes. Recent developments in many other applications have demonstrated these unique aluminas have applications in areas far beyond catalysts.

PURALOX and CATALOX are the trademarks for the aluminium oxides derived from the controlled activation of PURAL and CATAPAL high-purity alumina hydrates. PURAL and CATAPAL are the respective trademarks of synthetic, high-purity boehmite (AlOOH) and bayerite (Al(OH)³), manufactured in Brunsbüttel, Germany, and Lake Charles, USA. The proprietary process used in the preparation of these high-purity aluminium oxides allows Sasol to control many important physical properties and hence "tailor-make" a product for your needs. Both PURALOX and CATALOX are available as white, free flowing powders with high-purity and consistency. Due to the precisely controlled processing conditions during and after manufacturing these aluminium oxides, PURALOX and CATALOX make excellent starting materials for the catalyst industry. They provide excellent specific catalytic activities, high surface area stability and low attrition loss. PURALOX and CATALOX are arguably the best starting materials for the catalyst industry where consistency and an stable nature of the support is highly desired. These characteristics are of great importance for fluid and slurry bed applications. Due to their high thermal stability, PURALOX and CATALOX are widely used raw materials for wash coat formulations in environmental emission-control catalysts. Recent developments have found other suitable uses for these materials in applications outside catalysis such as polishing, chromatography, adsorbents and gas separation.
