METHOD OF PRODUCING CATALYST Russian patent published in 2016 - IPC B01J35/02 B01J37/00 B22F3/105 B29C67/00 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing a catalyst based on particles with size of cross section in range of 1-50 mm and combination of sizes in range of 0.5-5 using layer of additive produced by 3D printing technology, wherein method includes: (i) forming a layer of a powdered catalyst support material, containing aluminium oxide, metal aluminate, silicon dioxide, aluminosilicate, titanium dioxide, zirconium dioxide, zinc oxide or mixture thereof (ii) binding or fusing powder in said layer according to a predetermined pattern, (iii) repeating (i) and (ii) layer upon layer to form a shaped unit, and (iv) optionally applying a catalytic material to said shaped unit. Invention also relates to a catalyst for ammonium oxidation, obtained using disclosed method. Invention also relates to a method of using said catalyst, involving bringing a mixture of reagents into contact with moulded catalyst unit under conditions which enable to carry out a catalysed reaction, where catalysed reaction is selected from ammonia oxidation and nitrogen oxide decomposition reactions.

EFFECT: high catalyst efficiency.
