AEROSIL® fumed silica for catalyst carrier

AEROSIL® Fumed Silica and AEROXIDE® Fumed Metal Oxides are suitable for various areas of catalyst manufacturing. They serve:

• as a main constituent of carrier materials providing controlled surface area and porosity for the final catalytic system
• as a silica source for zeolite synthesis
• as a process aid, e.g. as a binder or rheology control agent during the forming process

Advantages offered for catalyst manufacturing are:

• High surface area and adjustable pore size distribution
• Controlled surface chemistry due to the continuous production process (e.g. fixed silanol group density)
• High purity and extraordinary heat stability

In addition to AEROSIL® Fumed Silica and AEROXIDE® Fumed Metal Oxides, several recently developed fumed mixed metal oxide grades are available in commercial quantities.

The AEROSIL® Fumed Silica and AEROXIDE® Fumed Metal Oxides product portfolio allows for the tailored production of a variety of catalysts. Applications range from their usage as washcoat components for environmental exhaust catalysts to pure catalyst carriers for metal catalysts in the chemical industry.
