FIELD: chemistry.

SUBSTANCE: present invention relates to a catalyst for steam reforming hydrocarbons and preparation method thereof. Described is a catalyst for steam reforming hydrocarbons, which contains nickel, titanium, boron, manganese, lanthanum and aluminium oxides, with the following content of components, wt %: nickel oxide 8.5-24.5; titanium oxide 0.05-2.1; boron oxide 0.1- 3.0; manganese oxide 0.01-2.8; lanthanum oxide 0.1-5.0; caesium oxide 0.1-2.0, aluminium oxide - the rest. Described is also a method of producing the catalyst by preparing a mixture containing alumina, titanium oxide, boric acid, manganese oxide, lanthanum oxide, caesium oxide, adding binder containing paraffin, wax and oleic acid, moulding a support in form of granules via slip casting at excess pressure 0.4-2 MPa at temperature 70-80°, curing in air and calcining the obtained support in two steps: calcining in ceramic moulds in a layer of alumina at temperature 1100-1200°C for 4-8 hours, followed by raising the temperature for one hour to temperature 1350-1420°C and calcining at given temperature for 2-4 hours. After calcining, the support is saturated with a solution of nickel, aluminium and/or lanthanum and caesium nitrates, drying and calcination of the catalyst mass at 400-500°C.

EFFECT: obtaining a catalyst with high selectivity, low susceptibility to soot formation, for use in reaction mixtures with high content of methane.
