Saint-Gobain NorPro High Surface Area (HSA) Catalyst Carrier SA Series High Purity Alumina

Some catalyst carriers in this series are available in monomodal or bi-modal pore options. Saint-Gobain NorPro provides a range of formed, higher surface area catalyst carrier. Surface areas from 10 m2/g to 400 m2g are typically based on high-purity raw materials. When needed, Saint-Gobain NorPro can incorporate unusual pore size distributions, including a high proportion of macroporosity. In recent years, we have developed strong, impact-resistant rings with outside diameters as small as 3 mm. Saint-Gobain NorPro manufactures its intermediate and high-surface area alumina catalysts in special shapes. Pentarings and short pentarings (wagon wheels) offer activity and geometric surface area advantages along with low pressure drop. Honeycomb rings are also available. Transition Phase Materials Very precise calcination temperature control together with careful choice of materials allows Saint-Gobain NorPro to manufacture phase-specific alumina carriers, e.g. material that is >90% theta-alumina. Materials Alumina carriers can be made from: Theta Delta Eta

Some catalyst carriers in this series are available in monomodal, bi-modal or tri-modal pore options. For many years, Saint-Gobain NorPro has been known for its range of very low surface area macroporous alpha-alumina-based carrier materials. Inert to their environment in most circumstances, the carriers play a vitally active role in many catalytic reactions. Other low-surface area catalyst carrier materials include silica, alumina-silica, zirconia, titania, silica, and silicon carbide. Saint-Gobain NorPro also offers a range of attrition-resistant, porous, low-surface area fluidizable aluminas as the basis of active and stable fluid bed catalysts. Particle sizes from 50 to 120 micron are available, with silica contents from 0 to 10%
