METHOD OF PRODUCTION OF SOLID SUBSTANCE CONTAINING ZEOLITE Russian patent published in 2009 - IPC C01B39/02 

FIELD: mining.

SUBSTANCE: invention refers to methods of zeolite production. The method of production of solid substance containing titanium-silicate-1 consists in stage (I): at least partial crystallisation of solid substance containing at least one zeolite out of synthesis mixture with production of mixture (I) including at least the said solid substance and also at least one template compound presenting tetrapropylammonia hydroxide as an additive; stage (II): concentration of solid substance which is present in mixture (I) by ultra-filtration with obtaining retentate and permeate; notably, that permeate contains the said at least one template compound; stage (III): agglomeration or granulation or agglomeration and granulation of particles of solid substance in retentate from stage (II); also permeate produced at stage (II) containing the said at least one template compound at least partially is returned to stage (I); while ultra-filtration is performed with implementing at least one membrane containing dividing layers with diametre of pores from 50 nm to 200 nm.

EFFECT: invention facilitates re-circulating template compounds to stage of re-crystallising.
