Titanium silicalite-1 containing granules, preparation methods thereof, suspension catalysts containing them and methods for using them in various chemical reactions

摘要

Production of granulates containing titanium silicalite-1 (I) comprises hydrothermal crystallization of a synthesis gel containing a silica source, a titanium dioxide source, a tetra-n-propylammonium compound, a base and water; spray drying or fluidized bed spray granulation drying the resultant (I) suspension, optionally after concentration and/or addition of other substances; and calcining the (I) granulate at 400-1000, preferably 500-750degreesC. An Independent claim is also included for (I) granulates per se.
