FIELD: process engineering.
SUBSTANCE: invention relates to method of catalyst production. Produced catalyst comprises oxide carrier composed of complex spinel, i.e. Mg [Al, Fe]2O4 and active component, i.e. nickel. Proposed method comprises calcination of modified carrier. It differs from known processes in that oxide carrier surface is, first, impregnated with the solution of cerium or lanthanum salts or mix thereof taken in amount of 5.0-10.0 wt % per oxide carrier. Then, nickel is applied to calcine at 500°C so that catalyst containing 10 wt % of nickel is obtained. Note here that prior to impregnation said oxide carrier is subjected to hydrothermal treatment at partial pressure of steam equal to 1.8-2.0 MPa and gradual increase in reaction zone temperature to 800-900°C at heating rate of 10 degree/min.
EFFECT: higher resistance to coke formation and mechanical strength.
