    Abstract: Shaped bodies of a molecular sieve zeolite having an improved mechanical hardness greater than 5 kp are produced by spraying an unstable silicic acid sol as the binder on to a zone of the rotating plate of a granulating device and concurrently applying the pulverized zeolite particles to another zone of the rotating plate, while avoiding the formation of a plastic mass, and the thus produced shaped bodies are dried and activated according to the disclosed process. The unstable silicic acid sol has a silicic acid content greater than 10 percent by weight and a BET surface greater than 150 m2/g.

    Abstract: Production of a titanium-containing zeolite comprises: (a) hydrolyzing a mixture of hydrolyzable silicon (Si) and titanium (Ti) compounds with a quaternary ammonium base in an aqueous medium in amounts such that the Si/Ti molar ratio is at least 30 and the nitrogen/silicon (N/Si) molar ratio is 0.12-0.2; and (b) crystallizing the resulting gel at 150-220 degrees C for less than 3 days. An Independent claim is also included for a Ti-containing zeolite produced by the above process, having a primary crystallite size of 0.1-2.0 mu m.
