Catalyst Carriers And Binders

Grace LUDOX® colloidal silica is an effective binder and carrier for catalytic materials. LUDOX® colloidal silica provides the following benefits:

LUDOX® colloidal silica also is useful to prepare catalysts for cracking and disproportionating hydrocarbons. A catalyst with higher concentrations of alumina can be prepared by simultaneously precipitating alumina and gelling the colloidal silica to form a product of any desired alumina-to-silica ratio. LUDOX® HS and AS colloidal silica are the grades normally used for this application. To select the right grade of LUDOX® colloidal silica for your specific needs, please contact your Grace representative.
