METHOD AND APPARATUS FOR PRODUCING PROTECTED CATALYST PARTICLES USING MOLTEN ORGANIC SUBSTANCE Russian patent published in 2014 - IPC B01J33/00 B01J23/75 C07C1/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of treating an active Fischer-Tropsch catalyst and an apparatus for preparing and treating said catalyst. The method of treating an active catalyst includes loading a mixture of particles of an active Fischer-Tropsch catalyst and molten wax, which is at a temperature T₁ and which sets at a lower temperature T₂ lying between 70°C and 140°C, where T₂<T₁, into a plurality of moulds; at least partial immersion of the moulds into a cooling liquid to cool the organic substance to a temperature T₃, where T₃≤T₂, to obtain cast products in form of candles with a volume of less than 140 ml but more than 2 ml each, having an organic substance matrix in which particles of the active catalyst are dispersed such that the catalyst particles are coated with wax; removing the cast products from the moulds; loading the mixture into moulds, immersing the moulds into a cooling liquid and removing the cast products form the mould in a casting machine. The apparatus includes equipment for preparing or regenerating the catalyst, including a reservoir for applying a coating onto the catalyst; a transportation means for transferring the mixture of particles of the active catalyst and molten organic substance from the reservoir for applying a coating onto the catalyst; a casting machine for producing cast products in form of candles which includes a plurality of moulds into which the transportation means can unload the mixture of particles of the active catalyst and molten organic substance, and a cooling bath capable of holding a cooling liquid into which the moulds can be immersed at least partially.

EFFECT: method and apparatus enables to safely and easily move a catalyst from the production site to the point of use without losing activity.
