FIELD: oil, gas and coke industry.
SUBSTANCE: invention relates to a method and device for producing synthesis gas. Method of producing synthesis gas (5) is carried out by steam reforming, in which in order to produce low-nitrogen feed (4) for burner-fired steam reformer (D), from starting material (1) containing hydrocarbons and nitrogen, nitrogen is separated to form hydrocarbon-containing residual gas (2) which subsequently serves as fuel (6). Nitrogen is separated from the starting material by adsorption (N), and hydrocarbon-containing residual gas (2) is used to heat steam reformer (D).
EFFECT: technical result consists in obtaining gaseous products with high purity from the produced synthesis gas, as well as in the separation of nitrogen from the produced synthesis gas at a relatively low cost.
