Catalyst carriers are porous substrate materials that are used in the 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, oilsand lubricants. The refining process involves cracking hydrocarbons at high temperatures and pressures in the presence of a catalyst.

Alumina is used in the production of catalyst carriers because of its high temperature inert properties, making it a suitable substrate material to host the catalyst while not degrading its function and also not interacting with the chemical reactants.   The pore structure of the catalyst carrier is  critically important in the hydrocarbon cracking process, since it is where the reaction is catalyzed.   Certain characteristics of the alumina raw material, such as particle size distribution, can influence the pore size and distribution and therefore  consistency is vital to making an effective carrier substrate.

Sinoal calcined aluminas for catalyst carrier applications include unground, continuous ground and batch ground products.  Our products feature tightly controlled particle size distributions and consistent surface areas to ensure a proper pore structure is achieved every time.  We also offer different purity levels, particularly related to Na2O content, to meet specific formulation needs.  Certain formulations also require a hydraulic ceramic binder and Sinoal offers 70% and 80% calcium aluminate cements to meet these needs.
