Much of the chemical industry employs processes that use either homogenous or heterogenous catalysts. Most reactions are performed with heterogeneous catalysts that are predominantly transition metals supported on ceramic carriers. Such carriers can be zeolite (aluminium silicate) or porous substrate materials made of alumina ceramics. These supports are mainly used by chemicals and petrochemicals industries for refining liquids and gases into intermediate and end-use products. Refineries around the world convert naturally occurring liquids, gases and intermediates into usable products such as fuels, chemicals, oils and lubricants. We have developed alumina products specifically for the manufacture of catalyst supports. These products are characterized by their high, 99.99% – 99.999%, purity.
