Abstract

Granulates which contain titanium silicalite-1 are composed of silicon dioxide, titanium dioxide and titanium silicalite-1 crystals. The granulates can be prepared by spray-drying or spray granulating the crystallization suspension. The granulates may be used as suspension catalysts, such as for the epoxidation of olefins using hydrogen peroxide.
