IRON-CONTAINING ZEOLITE, METHOD OF PRODUCING IRON-CONTAINING ZEOLITES AND METHOD FOR CATALYTIC REDUCTION OF NITROGEN OXIDES Russian patent published in 2016 - IPC B01J29/76 B01J29/72 B01D53/94 B01J37/02 

FIELD: technological processes.

SUBSTANCE: invention relates to method of preparing iron-containing zeolite material with topologies BEA, CHA, LEV, ZSM. Method consists in fact that zeolite material is doped with iron by means of gas-phase reaction using iron pentacarbonyl, wherein iron alloying is carried out in two steps: (i) processing in gas phase and (ii) thermal decomposition, and on the additional stage (iii) through zeolite material carrier gas flow at temperature of 500-1000 °C and pressure of 0.1 to 10 bar, gas-carrier is represented by water vapour air, inert gases or mixtures thereof.

EFFECT: technical result consists in production of iron-containing zeolite material with large specific surface and high hydrothermal stability.
