METHOD FOR PRODUCTION OF FERRITES-CHROMITES TRANSITIONAL ELEMENTS WITH SPINEL STRUCTURE Russian patent published in 2016 - IPC B01J37/04 B01J23/885 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing solid solutions with spinel structure based on ferrites and chromites of transitional elements and can be used in chemical industry in organic synthesis for production of butadiene and hydrocarbons from synthesis gas. Problem is solved by the method of producing an efficient catalyst based on ferrite-chromite of nickel (II) and copper (II) by means of homogenization of initial oxides of nickel (II), iron (III), chromium (III) with introduction in the mixture of oxides of a mineralizer - potassium chloride with additional introduction of copper (II) oxide, briquetting under the pressure of 15 MPa and thermal treatment of the obtained mixture of oxides at the temperature of 760-800 °C.

EFFECT: technical result of introduction of copper (II) oxide is lowering the temperature of thermal treatment.
