FIELD: chemistry.
SUBSTANCE: invention relates to method for obtaining egg-shell catalyst, including the following stages: (i) soaking annealed substrate, containing metal aluminate, with nickel acetate-containing solution, at temperature ≥40°C and drying soaked substrate, (ii) annealing dry soaked substrate to form nickel oxide on substrate surface, and (ii) optionally, repetition of stages (i) and (ii) on substrate, coated with nickel oxide. Invention also relates to egg-shell catalytic material for steam hydrocarbon reforming, method for steam hydrocarbon reforming and method for methanation of gaseous hydrogen flow, containing CO and CO2.
EFFECT: minimising formation of greenhouse gases in the process of annealing.
