Improving chemical reactions

Catalysts - increasing mechanical stability

Colloidal silica is an ideal component in catalyst manufacturing thanks to its consistent, controlled surface area, particle size and high purity. Its excellent inorganic high temperature binding capability increases the mechanical stability of catalysts. Additionally, the chemical inertness of colloidal silica makes it an appropriate additive, as it does not affect the selectivity of the catalyst.

Catalysts are key components in a number of industries that rely on robust chemical processes. By using a catalyst, the activation energy of the chemical reaction can be reduced, which translates into more cost-efficient processes thanks to lower energy consumption.

As a good inorganic binder, colloidal silica can improve the properties of heterogeneous catalysts by enhancing their mechanical stability and extending their lifetime by increasing attrition resistance. Additionally, thanks to its chemical inertness, colloidal silica is appropriate as a binder in many different catalyst types.

Another use of colloidal silica is as support material for catalytically active substances. Colloidal silica is used to increase the surface area and control the pore size and porosity of the catalyst, thereby enhancing the utilization of the catalytically active substances.

Finally, thanks to their high purity and product consistency, sodium and electrolyte-free colloidal silica dispersions are ideal raw materials (i.e., pure silica source) in the synthesis of zeolites.
