PROCESS FOR THE PRODUCTION OF MOLECULAR SIEVE GRANULATES

A process for the production of silica-bound zeolite granulates is disclosed, wherein zeolite to be formed into a granulate is mixed with silica sol. The process is carried out by adding aqueous alkali metal silicate to the silica sol immediately before the silica sol is mixed with the solid zeolite...

Beschreibung
Zusammenfassung:	A process for the production of silica-bound zeolite granulates is disclosed, wherein zeolite to be formed into a granulate is mixed with silica sol. The process is carried out by adding aqueous alkali metal silicate to the silica sol immediately before the silica sol is mixed with the solid zeolite to be granulated. By the described process, granulates of various grain sizes can be obtained, and the resultant granulates can have a narrow grain size distribution.
