OXIDE-NICKEL CATALYST PRODUCTION METHOD Russian patent published in 2017 - IPC B01J37/00 B01J37/02 B01J21/04 B01J23/755 

FIELD: chemistry.

SUBSTANCE: oxide-nickel catalyst production method includes the impregnating of alumina-based carrier with the nickel nitrate solution, further drying at the temperature of 100-120°C and calcination at the temperature of 450-500°C. The method is characterized in that, the carrier is preliminarily impregnated with the ammonia-carbonate solution with the concentration of NH₃ - 31-40 g/l, CO₂ - 81-90 g/l. Then, the carrier is washed with distilled water and the single hydrothermal treatment is carried out in the solution of nickel nitrate with the concentration of 100-300 g/l at the temperature of 50-80°C for 2-4 hours. In the method, the thickness of the surface catalytically active layer is formed as necessary within the range of 350-650 mcm.

EFFECT: oxide-nickel catalyst production method creation on the inert carrier with the controlled thickness of the surface oxide-nickel layer in the industrial volumes, the method is characterized by the reduction of the catalyst production technological stages number and the increase of its service life.
