CATALYST, ITS PREPARATION METHOD, AND PROCESS OF AMMONIA OXIDATION Russian patent published in 2021 - IPC B01J23/78 B01J23/887 B01J23/84 B01J37/04 B01J37/08 C01B21/26 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst of a block cellular structure for the oxidation of ammonia to nitric oxide (II), which is a mixed oxide of the general formula (MeO)_x(Mg_2-yMp_yAl₄Si₅O₁₈)_1-x, where x=0.01-0.2, y=0.05-0.2, MeO is the active component of the catalyst, Me is Mn, Fe, Co, Ni, Cu, Cr, V and/or their mixtures, Mr is the promoter, which is a mixture of Fe, K, Na, Li, Ca, Ti, and Mg_2-yMp_yAl₄Si₅O₁₈ is the forming component of the catalyst, which has the cordierite structure. The invention also relates to a method for preparing a catalyst of a block cellular structure for the oxidation of ammonia to nitric oxide (II) and to the process of oxidation of ammonia to nitric oxide (II).

EFFECT: an increase in the activity and strength of the catalyst, an increase in the run time of the catalyst grids as part of a two-stage catalytic system.
