FIELD: chemistry.
SUBSTANCE: proposed method of synthesis of iron-containing beta zeolite with the mole fraction ratios of silica and aluminium oxide (SAR) comprising from 5 to 20, without organic structure-forming agent (SDA), except for any seed material. Beta zeolite has a silica utilisation factor of more than 30% with respect to the synthesis mixture. Iron is present in an amount of, at least, 0.5 wt % with, at least, 60% of iron present as an isolated cation at the center of the exchange.
EFFECT: producing zeolite effective in the processes of catalytic reduction of nitrogen oxides in the exhaust gases.
