Catalyst Carriers

SIPERNAT® Precipitated Amorphous 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,
⇒ and as a main constituent for carrier materials to provide a controlled surface area and porosity for the final catalytic system.

Advantages offered for carrier manufacturing are:

⇒ High surface area and controlled pore size distribution available as the raw material to the shape or monolith forming process.
⇒ 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® silica offers superior processability during extrusion.

SIPERNAT® precipitated 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 bimodal pore size distributions that allow better percolation of reaction media within the final catalyst extrudate.
