METHOD FOR CATALYTIC OXIDATION OF AMMONIA Russian patent published in 2013 - IPC C01B21/26 B01J23/42 

FIELD: chemistry.

SUBSTANCE: method for catalytic oxidation of ammonia involves passing an ammonia/air mixture through a two-step catalyst stack of an industrial assembly, having a catalyst stack of platinoid meshes of first oxidation state, a catalyst of second oxidation state which is a stack of meshes of stainless steel with thread diameter of 0.10-0.30 mm whose surface if coated with platinum and placed against the catalyst stack of first oxidation state, as well as a platinum collector, having a stack of 3-5 platinum wire gauzes containing a component selected from: PdW (95/5); Pd/Ni (95/5).

EFFECT: invention reduces inclusion of platinoids while maintaining high degree of conversion of ammonia, reduces the level of irrecoverable loss of platinoids and the ammonia slip value.
