SIPERNAT® Specialty Silica for Catalyst Carrier Applications

SIPERNAT® Specialty Silica grades are suitable for various areas of catalyst manufacturing. They serve:

• As a silica source for zeolite synthesis
• As a process aid, e.g. as a binder or rheology control agent during slurry processing
• As a main constituent for catalyst carrier materials to provide a controlled surface area and porosity for the final catalytic system

Advantages offered for manufacturing of catalyst supports are:

• High surface area and controlled pore size distribution help to design superior characteristics of shaped catalyst supports or monoliths

• Pore size distributions tunability, where micro-, meso-, and macro-pores can be tailored
• Surface properties can be easily modified by means of the chemistry of surface silanol groups
• SIPERNAT® specialty silica offer superior processability during extrusion

SIPERNAT® specialty silica grades provide a wide range of fine-sized silica materials that can be formed to appropriate shape size and geometry by the catalyst manufacturer. Choice of appropriate recipes and extrusion conditions help to tailor pore size distributions that allow better percolation of reaction media within the final catalyst extrudate.
