COMPOSITION CAPABLE OF REDUCING CO AND NOEMISSIONS, ITS PRODUCTION METHOD AND USE, AND METHOD FOR CATALYTIC CRACKING IN FLUIDIZED LAYER Russian patent published in 2022 - IPC B01J23/745 B01J23/75 B01J32/00 B01J37/08 C10G11/00 

FIELD: catalytic cracking.

SUBSTANCE: present invention relates to the field of catalytic cracking, in particular to a composition capable of reducing CO and NOx emissions, a method for the production of a composition capable of reducing CO and NOx emissions, a composition capable of reducing CO and NOx emissions, produced by this method, the use of a composition capable of reducing CO and NOx emissions, and a method for catalytic cracking in a fluidized layer (FCC). A composition capable of reducing CO and NOx emissions is described, containing: an inorganic oxide-based carrier and the first element-metal applied to the inorganic oxide-based carrier. The first element-metal is selected from a group consisting of elements-base metals of group VIII. The first element-metal includes Fe and Co. The mass ratio of Fe to Co is 1:(0.1-10) per oxides. The composition also contains the second element-metal applied to the inorganic oxide-based carrier. The second metal is at least one metal selected from a group consisting of elements-metals of group IA and/or IIA. Per the total weight of the composition, the inorganic oxide-based carrier is present in the amount of 10-90 wt. %. Per oxides, the first element-metal is present in the amount of 0.5-50 wt. %, and the second element-metal is present in the amount of 0.5-20 wt. %.

EFFECT: development of an additive suitable for the reduction in contaminant emission in flue gas of a device with incomplete regeneration for the additional reduction in NOx emission in flue gas.
