Patent ID: 8449812

Claim:
Process for the production of a titanium silicalite shaped article comprising: a) preparing a synthesis gel containing a SiO 2 source, a TiO 2 source selected from the group consisting of tetraalkylorthotitanates and silicon-titanium mixed oxides obtainable by flame hydrolysis of a mixture of SiCl 4 and TiCl 4 , a template compound and water, b) crystallizing the synthesis gel under hydrothermal conditions to obtain a crystal suspension containing titanium silicalite, c) drying the titanium silicalite from step b) at a temperature below the decomposition temperature of the template compound, d) preparing a formable mass containing a binder, a paste-forming agent and product from step c), said product being non-calcined and containing said template compound, e) forming of the mass from step d) into a green shaped article, said mass being not yet calcined, f) optionally drying, and g) calcining the green shaped article to thereby remove said template compound, characterized in that the template compound is chosen in a way that the titanium silicalite obtained by step b) exhibits MFI, MEL or β-zeolite structure and the calcination step takes place after the formation of the green shaped article.
