SHAPED CARRIERS
Most modern, highly selective catalytic processes require materials with tailored porosity and well-defined surface properties, therefore, the choice of the most suitable support material is the first crucial step in the preparation of advanced heterogeneous catalysts.
In addition to alumina powders, Sasol as a specialties business also offers shaped carriers such as spheres, extrudates, and tablets.
A key advantage of Sasol’s aluminas is their ability to form excellent supports. This application makes use of the aluminas’ ability to peptize in the presence of monoprotic acids. A variety of extrudate properties can be obtained by using different grades of PURAL and CATAPAL aluminas and by controlling the formulation and extrusion variables. The individual properties of Sasol Alumina powders, such as level of purity, porosity, surface area and dopants are preserved during the shaping processes. Sasol Alumina shaped carriers are available as extrudates, spheres and tablets in various sizes and shapes. In addition individual parameters can be modified at the customer’s request.
