FIELD: production of gas mixture containing hydrogen and carbon oxide from hydrocarbon raw material.
SUBSTANCE: proposed method includes the following stages: (a) partial oxidation of part of raw material for obtaining the first gaseous mixture from hydrogen and carbon oxide; (b) catalytic vapor reforming of part of gaseous raw material in convective vapor reforming furnace provided with tubular reactor with one or more tubes containing reforming catalyst. Outer surface of tubular reactor tubes is used for cooling the hot gas obtained at stage (a). Surface of these tubes is made from metal alloy containing 0-20 mass-% of iron, 1-5 mass-% of silicon, 0-5 mass-% of aluminum, 20-50 mass-% of chromium and at least 35 mass-% of nickel.
EFFECT: reduction of coke formation and erosion of outer surfaces of reactor tubes.
