Abstract

A process for preparing an extrudable composition comprising a titanium-containing zeolitic material having framework type MWW, the process comprising providing a titanium-containing zeolitic material having framework type MWW, having a water absorption capacity of at least 11 weight-%, subjecting the titanium-containing zeolitic material having framework type MWW an acid treatment, optionally incorporating zinc in the acid-treated titanium-containing zeolitic material having framework type MWW; preparing a composition comprising the titanium-containing zeolitic material having framework type MWW obtained from (ii) or (iii), a precursor of a silica binder, water, and a kneading agent, wherein the composition does not comprise a polyethylene oxide.
